Abstract

A novel 40Ni-added germanotungstate, Cs8K14Na3H3{[Ni6(OH)3(H2O)6(B-α-GeW9O34)]2[Ni86-O)(μ2-OH)23-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.
