Abstract ：
Ln-containing polyoxoniobates (PONbs) have appealing applications in luminescence, information encryption and magnetic fields, but the synthesis of PONbs containing high-nuclearity Ln-O clusters is challenging due to the easy hydrolysis of Ln3 + ions in alkaline environments. In this paper, we are able to integrate CO3 2- and high-nuclearity Ln-O clusters into PONb to construct an inorganic giant Eu19 -embedded PONb H49 K16 Na13 (H2 O)63 [Eu21 O2 (OH)7 (H2 O)5 (Nb7 O22 )10 (Nb2 O6 )2 (CO3 )18 ] 91H2 O ( 1 ), which contains the highest nuclearity Eu-O clusters and the largest number of Eu3 + ions among PONbs. In addition, the film that was prepared by mixing 1 with gelatin and glycerol, exhibits reversible luminescence switching behavior under acid/alkali stimulation and has been used to create a fluorescence-encoded information approach. This work paves a feasible strategy for the construction of high-nuclearity Ln-O cluster-containing PONbs and the expansion of the application of Ln-containing PONbs in information encryption.

Abstract ：
The integration of high-nuclearity lanthanide-oxo (Ln-O) clusters into polyoxotungstates (POTs) presents a formidable synthetic challenge due to intricate assembly mechanisms and the labile nature of lanthanide coordination. Herein, we present an innovative alkaline-mediated templating strategy for constructing unprecedented Ln-oxo-cluster-encapsulated POTs through the synergistic assembly of lacunary polyoxotungstate precursors with in situ generated Ln-oxo clusters. This approach employs basic N-containing ligands and selenite (SeO32-) anions as synergistic structure-directing agents. Guided by this approach, we have successfully synthesized two series of giant Ln21-oxo-cluster-embedded polyoxotungstates, H23K30(H2O)18{[Ln21(H2O)9(WO6)(SeO3)6][Ln3(SeO3)2]2(GeW10O38)9}solvent (1-Ln) (Ln = Eu, Gd, Tb, Dy) and H27Na3K21(H2O)11(MePIP)2{[Ln21(H2O)9(WO6)(SeO3)6][Ln3(SeO3)2]2(GeW10O38)9}solvent (2-Ln) (Ln = Eu, Tb, MePIP = N-methylpiperazine). Notably, these compounds feature a rare pinwheel-shaped high-nuclearity Ln21-oxo-cluster-embedded polyanion, {[Ln21(H2O)9(WO6)(SeO3)6][Ln3(SeO3)2]2(GeW10O38)9} ({Ln27Se10Ge9W91}), with a three-layered sandwich structure. Compounds 1-Eu and 2-Eu exhibit distinct proton conduction properties due to their different packing structures. In particular, 1-Eu demonstrates a high single-crystal proton conductivity of 1.8 x 10-2 S cm-1 at 98% RH and 25 degrees C along the [001] channel direction, outperforming most crystalline porous materials. Additionally, 1-Eu exhibits temperature-dependent fluorescence. The 1-Eu0.25Dy0.75 sample can emit macroscopic white light under blue irradiation. This work provides a feasible strategy for constructing high-nuclearity Ln-oxo-cluster-containing POTs and expands their application in smart proton conductive materials and multicolor luminescent systems.

Abstract ：
Fabrication of gas sensors with high sensibility appears particularly important due to the urgent demand for toxic gases monitoring in public safety and atmosphere detection, especially for the detection requirement of ultra-low concentration gases. Here, we present a rare three-dimensional (3D) all-inorganic polyoxoniobate (PONb) framework based on {Cu4@Nb29} secondary building units linked with both tetranuclear {Cu4(OH)5} clusters and mononuclear [Cu(H2O)]2+ units. Remarkably, this 3D PONb framework exhibits an ultrasensitive response to NH3 with a lowest limit of detection of 1.64 ppt up to now. Furthermore, the NH3 induced single-crystal-to-single-crystal transformation as well as density functional theory analysis reveal that the strong coordination affinity of [Cu(H2O)]2+ linker for NH3, along with more injection of charge into the framework, results in a ultrasensitivity chemiresistive responses to NH3, at atomic-level insight.

Abstract ：
The integration of the rich electronic properties of 3d-4f heterometallic clusters with rigid and diamagnetic polyoxometalates is of great interest and is expected to yield novel materials with enhanced properties due to synergistic effects. For the first time, the study succeeds in introducing fluorescent Zn-Ln heterometallic clusters into polyoxoniobates (PONbs), forming a family of rare giant heterometallic PONbs with various architectures, including 78-metal {Zn10Eu8Nb60}, 112-metal {Zn16Ln8Nb88} (Ln = La, Y), and 165-metal {Na2Zn29Ln12Nb122} (Ln = Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho). These heterometallic PONbs exhibit many appealing structural features and unique building blocks. Particularly, they are the largest 3d-4f heterometallic PONbs and also the PONbs incorporating the largest number of 3d-4f metal ions and the highest-nuclearity 3d-4f clusters known to date. Furthermore, the combination of PONbs and Zn-Ln clusters renders these new-type heterometallic PONbs multicolor luminescent characteristics and high fluorescence quantum yields, making them promising candidate cluster molecules for responsive photonic barcodes.

Abstract ：
The incorporation of 3d-5p heterometallic clusters into polyoxotungstates not only enables the construction of novel and intriguing structures but also enhances the resultant materials with exceptional properties. Here, we present an unique strontium-bridged purely inorganic two-dimensional layered polyoxotungstate, H7Sr2.5(H2O)15.5[Ni7Sb6O9(OH)6(B-alpha-SiW9O34)2]& sdot;25.5H2O (1), which is composed of a sandwich-type thirteennuclear Ni-Sb heterometallic cluster {Ni7Sb6} and two {B-alpha-SiW9O34} units. Notably, compound 1 undergoes a single-crystal-to-single-crystal transformation, accompanied by the partial substitution of Sr2+ ions with Co2+ ions, resulting in a transition from a two-dimensional to a three-dimensional structure while maintaining excellent crystallinity. This process provides an opportunity to elucidate the ions exchange mechanism at the atomic level. Furthermore, electrochemical impedance studies reveal that 1 exhibits good proton conductivity, reaching 1.40 x 10-3 S cm- 1, under conditions of 85 degrees C and 98 % relative humidity.

Abstract ：
In this work, cation vacancies induced the tetrahedral distortion, enhancing the second harmonic generation (SHG) response in the diamond-like (DL) structure compounds. Concretely, the high valence and electronegativity of P5+ were introduced to substitute the Ge4+ in Cd4GeS6, which shows a general SHG response of 1.1 x AgGaS2 (AGS) at 2050 nm. Thus, the isomorphic defective DL Cd3.5PS6 was obtained with inherent Cd2+ vacancies, leading to an 8.5-fold increase in [CdS4] tetrahedral distortion degree than Cd4GeS6. As a result, Cd3.5PS6 has a high SHG response of 2 x AGS at 2050 nm and a laser-induced damage threshold (LIDT) of 9.4 x AGS. Furthermore, equivalent Hg2+ substitution concentrates Cd2+ vacancies at the Cd(2) site, leading to a 2.66-fold [CdS4] tetrahedral distortion degree than Cd3.5PS6. Consequently, Hg0.5Cd3PS6 possesses a high SHG response of 2.73 x AGS at 2050 nm and LIDT of 5 x AGS with a birefringence of 0.076@2050 nm. The results indicate that the cation vacancies and radius scale of mixed atoms provide effective ways to design high-performance nonlinear optical crystals.

Abstract ：
A series of novel cage-like transition-metal (TM) incorporated heteropolyoxoniobates {TM4Nb64O200} (1-TM, TM = Ni, Cu, Mn, Cd) were hydrothermally synthesized and isolated as salts of mixed K+ and [CN3H6]+. As a result of transition metal ions incorporation, the charge distribution, redox potential, and active sites of the formed polyoxoniobates (PONbs) are variants, leading to differences in their electrocatalytic hydrogen evolution reaction (HER). Among these compounds, 1-Ni showed the best HER activity with an overpotential of 560 mV at 10 mA cm-2 and a minimum Tafel slope of 405.8 mV dec-1.

A Tm(III)-rich silicotungstate Na{Tm3(H2O)17[Tm2(H2O)7(Si2W18O66)]}35H2O (Tm 5 Si 2 W 18 ) based on the open Wells-Dawson-type [Si2W18O66]16- building unit was synthesized by the reaction of Na10[alpha-SiW9O34]18H2O, itaconic acid, and TmCl3 in a HAc/NaAc buffer solution. Five kinds of Tm(III) ions were found in this compound and further linked the {Tm2Si2W18} subunit to form an interesting wavy 1D chain structure, which achieved the introduction of more lanthanide (Ln) ions into the [Si2W18O66]16- unit for the first time. Tm 5 Si 2 W 18 contains multiple exposed Tm-metal active sites, making it an efficient catalyst for the acetalization of 2-aminobenzamides/2-aminobenzenesulphonamides with aldehydes. A series of 2,3-dihydroquinazolinones and 3,4-dihydro-2H-1,2,4-benzothiadiazine-1,1-dioxides could be obtained in excellent yields under green and mild conditions.

Abstract ：
In the past, the synthesis of polyoxometalate (POM)-templated silver nanoclusters typically relied on the use of organic salts of POMs as starting templates, thereby limiting the solvent selectivity in the synthesis. The utilization of pure-inorganic POMs as starting templates in developing novel POM-templated silver nanoclusters has been neglected. Herein, we have used pure-inorganic polyoxoniobates as a starting template to synthesize a new silver nanocluster H4[Nb6O19@Ag40(iPrS)28S4] (Ag40) (iPrS = isopropylthiolate). Single-crystal X-ray diffraction analysis showed that the silver nanocluster exhibits a remarkable core-shell structure featuring a Lindqvist-type [Nb6O19]8- polyanion as a template, surrounded by 40-nucleated silver ions as the metal shell and capped by iPrS- ligands. Interestingly, the silver nanocluster exhibits significant fluorescence properties at low temperatures, demonstrating temperature-dependent fluorescence, making it a potential candidate for temperature sensing. This work provides a new strategy for new POM-templated silver nanoclusters by using pure-inorganic POMs as starting templates. It also offers new insights into the anionic template method for synthesizing silver nanoclusters.
