Abstract

A new bisupporting metal-oxygen cluster with bicapped pseudo-Keggin compound [CuII{Cl0.5Cl(phen)}]2 {[PMoV6MoVI6O40(VIVO)2][CuII(phen)2]2}·2H2O (phen = 1,10-phenathroline) has been synthesized by hydrothermal method and characterized by elemental analysis, IR spectroscopy, TGA, XRPD, and single-crystal X-ray diffraction. The polyoxoanion consists of a bicapped vanadium Keggin polyoxoanion and two {[Cu(phen)]2}2+ subunits producing bisupporting bicapped Keggin-polyoxometalate structure. The isolated dinuclear unit [CuII{Cl0.5Cl(phen)}2]+ acts as the countercation in title compound. In the crystal structure π - π stacking interactions, multiform C-H···O and O-H···O hydrogen bonds lead to a three-dimensional network.
