Abstract

The reaction of [VO(acac)2], methylenediphosphonic acid and triethylamine in acetonitrile at 110°C for 60 h yields (Et3NH)2-[(VO)2(acac)2(O 3PCH2PO3)] (1). The structure of 1 consists of two {VO(acac)} moieties linked by a methylenediphosphonate group in the bisbidentate bridging mode. The {(VO)2(O3PCH2PO3)} core of 1 provides a fundamental structural motif for one-dimensional oxovanadium methylenediphosphonate phases. Crystal data: C23H48N2O12P2V 2: orthorhombic P22121, a = 9.767(2), b = 17.189(3), c = 20.736(4) Å, V = 3481.3(12) Å3, Z = 4, Dcalc = 1.35 g cm-3; structure solution and refinement based on 2022 reflections converged at R = 0.068.
