Abstract ：
Herein, cobalt ammine complexes are combined with alkali-resistant polyoxoniobates (PONbs) at the molecular level to obtain two new organic-inorganic hybrid Co-containing PONbs with the same polyanions but different Co contents. The Co-containing PONb with higher Co content exhibits superior hydrogen evolution reaction (HER) activity under highly alkaline conditions, which is better than the results for the similar Cu-containing PONb, highlighting the critical role of cobalt in improving HER performance. This study provides a new insight into the relationship between the structural properties of metal complexes during electrocatalysis.

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.

Abstract ：
Two inorganic-organic hybrid polyoxotantalates, H-4[Na(H2O)(5)](2)[Co-II(en)(3)](2){[Co-III(en)](2)(Ta6O19)(2)}center dot 22H(2)O (1) and H2K2Na6 (H2O)(24){[Co-III(en)](2)(Ta6O19)(2)}33H(2)O (2) have been constructed from {[Co-III(en)(Ta6O19)](2)}(10-) ({Co2Ta12}) dimers. Compound 1 has a three-dimensional supramolecular framework with a pcu-type topology. Compound 2 possesses a three-dimensional structure composed of {Co2Ta12} dimers and alkali metal ions (Na+/K+) via coordination bonds. Polyoxotantalates 1 and 2 have been used as active materials for ITO/1/Ag and ITO/2/Ag RRAM devices. These devices exhibit stable non-volatile storage behavior and rewritable resistive switching with high ON/OFF ratios of 1.43 x 10(3) and 2.17 x 10(4) for 1-based and 2-based RRAM devices, respectively, and stable cyclic performance during 100-cycle stability tests. This discovery opens up new opportunities for the development of electrical bistability materials.

Abstract ：
Here, a case of bilayer heterojunction Pd-containing polyoxotungstate (POW), connecting a Te3Pd3 ring and an Anderson-like TeW6 cluster, has been synthesized. The Anderson-like cluster is the first example in POW. The coordination of Pd in the ring with the S atom on the sulfo group breaks the traditional coordination configuration of Pd and O in polyoxometalates (POMs), enriching the structural types of Pd-containing POMs. In addition, the hybrid bilayer heterojunction structure at the molecular level not only provides high thermal stability but also results in spatial arrangement anisotropy, leading to up to five times the anisotropic proton conductivity. © 2024 American Chemical Society.

Abstract ：
Polyoxometalates (POMs) have good potential for applications in different fields, including conducting materials, optics, and electrocatalysis. Of particular significance is the synthesis and development of addendum POMs. Molybdenum-oxo clusters, which are renowned for their diverse structures and electronic properties, were utilized to facilitate the synthesis of innovative materials. Herein, we employed presynthesized {XW9 Nb3O40} (X= Si/Ge) polyanions as secondary building units and different molybdenum-oxo clusters as linkers. Four new addendum POMs were constructed, including two dimeric compounds Cs10[H2(SiW9Nb3O40)2(Mo2O4C2O4)]19H2O (1) and Cs8[H4(GeW9Nb3O40)2(Mo2O4C2O4)]17H2O (2), and two tetrameric compounds Cs15(NH4)[(SiW9Nb3O40)4(Mo4O6)]42H2O (3) and Cs10K5[H(GeW9Nb3O40)4(Mo4O6)]39H2O (4). Notably, this is the first report of Mo/W/Nb ternary mixed-addendum POMs. In addition, compounds 3 and 4 facilitate the transfer of protons through extended hydrogen-bonding networks with conductivity values of 1.16 x 10-2 and 7.73 x 10-3 Scm-1 at 85 degrees C and 98% relative humidity, respectively. Furthermore, no discernible decline in conductivity was noted over the course of 10 h.

Abstract ：
Atomically precise low-nuclearity (n<10) silver nanoclusters (AgNCs) have garnered significant interest due to their size-dependent optical properties and diverse applications. However, their synthesis has remained challenging, primarily due to their inherent instability. The present study introduces a new feasible approach for clustering silver ions utilizing highly negative and redox-inert polyoxoniobates (PONbs) as all-inorganic ligands. This strategy not only enables the creation of novel Ag-PONb composite nanoclusters but also facilitates the synthesis of stable low-nuclearity AgNCs. Using this method, we have successfully synthesized a small octanuclear rhombic [Ag-8](6+) AgNC stabilized by six highly negative [LiNb27O75](14-) polyoxoanions. This marks the first PONb-protected superatomic AgNC, designated as {Ag-8@(LiNb27O75)(6)} (Ag-8@Nb-162), with an aesthetically spherical core-shell structure. The crystalline Ag-8@Nb-162 is stable under ambient conditions, What's more, it is water-soluble and able to maintain its molecular cluster structure intact in water. Further, the stable small [Ag-8](6+) AgNC has interesting temperature- and pH-dependent reversible fluorescence response, based on which a multiple optical encryption mode for anti-counterfeit technology was demonstrated. This work offers a promising avenue for the synthesis of fascinating and stable PONb-protected AgNCs and sheds light on the development of new-type optical functional materials.

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.
