Abstract ：
The development of core-shell nanoclusters with controllable composition is of utmost importance as the material properties depend on their constituent elements. However, precisely tuning their compositions at the atomic scale is not easily achieved because of the difficulty of using limited macroscopic synthetic methods for atomic-level modulation. In this work, we report an interesting example of precisely regu-lating the core composition of an inorganic core-shell-type cobalt polyoxoniobate [Co26Nb36O140]32- by controlling reaction conditions, in which the inner Co-core composition could be tune while retaining the outer Nb-shell composition of resulting product, leading to a series of isostructural species with a general formula of {Co26-nNb36 +nO140} ( n = 0-2). These rare species not only can display good powder and single-crystal proton conductivities, but also might provide helpful and atomic-level insights into the syntheses, structures and composition modifications of inorganic amorphous core-shell heterometal oxide nanoparticles.(c) 2023 Published by Elsevier B.V. on behalf of Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.

Abstract ：
By variation of the amount of GeO2, two organic-inorganic hybrid germanoniobate frameworks with 6-connected pcu and 10-connected bct topologies were constructed from peanut-shaped {alpha-Ge12Nb38} and {beta-Ge12Nb38} clusters, respectively. The {alpha-Ge12Nb38} and {beta-Ge12Nb38} clusters contain the most Ge centers of germanoniobates reported so far. The compounds exhibit proton conduction properties with a conductivity of 3.04 x 10(-4) Scm(-3) for 1 and 1.62 x 10(-4) Scm(-3) for 2 at 85 degrees C and 98% RH. The water vapor adsorption capacities for 1 and 2 are 5.86 and 4.40 mmolg(-1), respectively.

Abstract ：
Lanthanide ion contained metal-organic frameworks (MOFs) have garnered significant attention in the fields of solid-state lighting and chemical sensing due to their porous structure and distinctive optical properties. However, they also present challenges because of the limited photoluminescence (PL) intensity resulting from the parity-forbidden f-f transitions of lanthanide ions. Herein, the study reports a new heterometallic MOFs Ln3Li2L4 (Li-Ln-MOF, Ln = Y, Eu, Tb and Dy, L = deprotonated 1,3,5-tris(4-carboxyphenyl)benzene) with a Brunauer-Emmett-Teller (BET) surface area of 774.1 m2/g. The porous crystal structure of Li-Ln-MOF is characterized by three kinds of channels interpenetrating with each other. By employing ligand alternation and lanthanide ion alloying strategies, Li-Y1-xEux-MOF1 crystal isostructural with Li-Ln-MOF is synthesized by using 2,4,6-tris(4-carboxyphenyl)-1,3,5-triazine (H3TATB) as ligand. The Li-Y0.7Eu0.3-MOF1 crystal excels in the comprehensive performance with a BET surface area of 858.8 m2 g-1 and a near-unity PL quantum yield. The time density functional theory and natural transition orbitals calculations unravel that the outstanding optical properties Li-Y0.7Eu0.3-MOF1 originates from the charge transfer between TATB3- and Eu3+. Benefiting from the excellent comprehensive performance of Li-Y1-xEux-MOF1, the study reveals their potentials as single-composition white-light emission and fluorescent sensing probe for the detection of nitrobenzene. A strategy via ligand alteration is developed to achieve a near-unity photoluminescence quantum yield in lanthanide metal-organic frameworks (Ln-MOFs) with a porosity of up to 53.6%. Mechanistic investigation through theoretical calculation and time-resolved spectra unravel that Ln-MOF displayed outstanding optical properties ascribed to the charge transfer from the triple excited state of ligand to the Ln3+. image

Abstract ：
In this work, a novel organodiphosphate-containing inorganic-organic hybrid polyoxoniobate (PONb) ring {(PO3CH2CH2PO3H)(4)Nb8O16}(4-) (Nb8P8) has been achieved by a one-pot hydrothermal method. The ring is constructed from a tetragonal {Nb8O36} motif and four {PO3CH2CH2PO3H} ligands. Interestingly, Nb8P8 can be joined together via K-H2O clusters {K-2(H2O)(4)(OH)(2)} to form one-dimensional chains {[K-2(H2O)(4)(OH)(2)]Nb8P8}(n) and further linked by {Cu(en)(2)}(2+) (en = ethylenediamine) complexes, resulting in a three-dimensional supramolecular framework {[Cu(en)(2)](2)[K-2(H2O)(4)(OH)(2)]Nb8P8}3enH2O (1). 1 exhibits good chemical and thermal stability and has a high water vapor adsorption capacity of <= 224 cm(3) g(-1) (22.71 molmol(-1)) at 298 K, outperforming most of the known polyoxometalate-based materials. Impedance measurements prove that 1 can transfer protons with moderate conductivity. This study not only contributes to the structural diversity of organodiphosphate-containing PONbs and PONb rings but also provides a reference for the development of PONb-based materials with unique performance.

Abstract ：
Helical morphologies are widely observed in nature, however, it is very challenging to prepare artificial helical polymers. Especially, precisely understanding the structure information of artificial metal-free helical covalent inorganic polymers via single-crystal X-ray diffraction (SCXRD) analysis is rarely explored. Here, we successfully prepare a novel metal-free helical covalent inorganic polymer ({[Te(C6H5)2] [PO3(OH)]}n, named CityU-10) by introducing angular anions (HOPO32-) into traditional tellurium-oxygen chains. The dynamic reversibility of the reaction is realized through the introduction of organic tellurium precursor and the slow hydrolysis of polyphosphoric acid. High-quality and large-size single crystals of CityU-10 have been successfully characterized via SCXRD, where the same-handed helical inorganic polymer chains form a pseudo-two-dimensional layer via multiple hydrogen-bonding interactions. The left-handed layers and right-handed layers alternatively stack together through weak hydrogen bonds to form a three-dimensional supramolecular structure. The single crystals of CityU-10 are found to display promising optical properties with a large birefringence. Our results would offer new guidelines for designing and preparing new crystalline covalent polymers through tellurium-based chemistry. A metal-free helical covalent inorganic polymer (CityU-10) has been successfully prepared. Its crystal structure shows that the same-handed helical chains form a pseudo-two-dimensional layer via multiple hydrogen-bonding interactions. Then, the left-handed layers and right-handed layers alternatively stack together to form a three-dimensional supramolecular structure.image

Abstract ：
Two types of isostructural iron-cobalt/nickel-antimony-oxo tartrate cluster-based compounds, namely (H3O)(Me2NH2)[M(H2O)6]2[FeII2SbIII12(mu 4-O)3(mu 3-O)8(tta)6]center dot 6H2O (M = Co (1); Ni (3)), H5/3[Co2.5FeII4/3FeIII3(H2O)13SbV1/3FeIII2/3(mu 4-O)2(mu 3-O)4SbIII6(mu 3-O)2(tta)6]center dot 2H2O (2) and H2[Ni2.25FeII1.5FeIII3(H2O)14SbV0.25FeIII0.75(mu 4-O)2(mu 3-O)4SbIII6(mu 3-O)2(tta)6]center dot 2H2O (4) (H4tta = tartaric acid) were synthesized via simple solvothermal reactions. All the clusters in the structures adopt sandwich configurations, that is, bilayer sandwich configuration in 1 and 3 and monolayer sandwich configuration in 2 and 4. Interestingly, the monolayer sandwiched compounds 2 and 4 represent rare examples of cluster-based compounds containing mixed-valence Sb(III, V), whose center of the intermediate layer is the co-occupied [FexSbV1-x]. This is different from that of previously reported sandwich-type antimony-oxo clusters in which the center position is either occupied by a transition metal ion or a Sb(V) alone. Thus, the discovery of title compounds 2 and 4 makes the evolution of center metal ion more complete, that is, from M, MxSbV1-x to SbV. All the title compounds were fully characterized, and the photocatalysis, proton conduction and magnetism of compounds 2 and 4 were studied.

An inorganic hexalanthanide-oxo-cluster-encapsulated antimotungstate, K2Na3H43[Nd6(OH)6(H2O)6(B-alpha-SbW9O33)4]2 center dot 67H2O (1), has been successfully synthesized by a facile one-step hydrothermal reaction method. The tetrahedron-shaped two-shell {Nd6(OH)6(H2O)6(B-alpha-SbW9O33)4}(1a) polyanion is composed of a novel pure lanthanide-oxo {Nd6(mu 3-OH)6(H2O)6} octahedron and {(B-alpha-SbW9O33)4} tetrahedron. After being effectively loaded onto a glassy carbon electrode (GCE) by electrostatic adsorption using polydiallyldimethyl ammonium chloride (PDDA)-functionalized multi-walled carbon nanotubes (MWCNTs), compound 1 exhibits electrochemical activity for the reduction of bromate ions with good selectivity, a high sensitivity of 186 mu A mM-1 and a detection limit that has reached 1.9 mu M. To the best of our knowledge, this is the first example of an amperometric bromate sensor based on Ln-containing antimotungstates, which will provide new materials for electrochemical sensors. An inorganic antimotungstate 1 is constructed from tetrahedron-shaped two-shell {Nd6(OH)6(H2O)6(B-alpha-SbW9O33)4} polyanions. Compound 1 exhibits electrochemical activity for the reduction of BrO3- with good selectivity, high sensitivity and low detection limit.

Abstract ：
Herein, we report the synthesis, crystal structure, and optical properties of a metal-free three-dimensional (3D) inorganic covalent framework ((H(2)en)-[Si-(B4O9)], named CityU-11, where H(2)en is the abbreviation for ethanediamine). With the assistance of a tiny amount of F- ions and the selection of SiO2 as Si sources, single crystals of CityU-11 can be successfully prepared under solvothermal conditions. The precise structure information on CityU-11 has been disclosed through both single-crystal X-ray diffraction (SCXRD) and low-dose high-resolution transmission electron microscopy (LD-HRTEM). The SCXRD results showed that CityU-11 crystallized in the noncentrosymmetric space group of Pnn2, while LD-HRTEM suggested that CityU-11 possessed almost the same interplanar distances of 0.6 nm for both (200) and (020) crystal planes, which finely matched with the double peaks of 2 theta = 15 degrees in the pattern of its powder X-ray diffraction (PXRD). CityU-11 also displayed an interesting optical property with a moderate birefringence of 0.0258@550 nm.
