Abstract

The hydrothermal reaction of Cu(II), Na3VO4, and methylenediphosphonic acid provided a trimetallic hybrid oxide, Na 2[CuV2O2(H2O)2(O 3PCH2PO3)2] (1). The structure consists of a three-dimensional {CuV2O2(H2O)2(O3PCH2PO3)2}n-2n framework with charge-compensating Na+ cations entrained within the void spaces. The compound is paramagnetic, and the temperature dependence of the magnetic susceptibility was fit to the Curie-Weiss law. The effective magnetic moment of 2.92 μB at room temperature is consistent with three weakly interacting S = 1/2 spins, corresponding to one Cu(II) and two V(IV) sites.
