Synthesis of a Ag-bridged V-centred tungstovanadate dimer capped by [Ag(phen)] units

A Ag-bridged V-centred tungstovanadate dimer capped by [Ag(phen)] unit, [Ag(phen)2]7{Ag[Ag(phen)(VW10V2O40)]2} (1) (phen = 1,10-phenanthroline), has been hydrothermally synthesized, and characterized by IR, TG and single-crystal X-ray diffraction. Structural analysis reveals that the compound is composed of one dimeric {Ag[Ag(phen)(VW10V2O40)]2}7− anion and seven [Ag(phen)2]+ cations, which represents the first V-centred tungstovanadate grafted by transition metal coordination polymers. Furthermore, the electrochemical properties of 1 have been studied in the paper.
