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, D_calc = 1.35 g cm^-3; structure solution and refinement based on 2022 reflections converged at R = 0.068.
