Abstract

A novel 40Ni-added germanotungstate, Cs₈K₁₄Na₃H₃{[Ni₆(OH)₃(H₂O)₆(B-α-GeW₉O₃₄)]₂[Ni₈(μ₆-O)(μ₂-OH)₂ (μ₃-OH)₂(H₂O)B₂O₃(OH)₂(B-α-GeW₉O₃₄)₂]}₂·84H₂O (1), was made by the reaction of the trivacant [A-α-GeW₉O₃₄]^10- ({GeW₉}) precursor with Ni²⁺ cations and B₅O₈^-, and systematically investigated by Fourier-transform infrared spectroscopy, elemental analysis, thermogravimetric analysis, and powder X-ray diffraction. Single crystal X-ray analysis indicates that the polyoxoanion of 1 is a novel octamer constructed by {Ni₆GeW₉} and {Ni₈(GeW₉)₂} structural building units via Ni-O═W linkages. The magnetic behavior shows the existence of overall ferromagnetic interactions among the Ni²⁺ centers in compound 1. Photocatalytic H₂ production studies have implied that 1 can work as a heterogeneous catalyst for hydrogen production with decent robustness and recyclability.
