Abstract

We have extended our research interest on titanium oxyphosphates (M^II(TiO)₂(PO₄)₂, with M^II = Mg, Fe, Co, Ni, Cu, Zn) to vanadium oxyphosphates M^II(V^IVO)₂(PO₄)₂ (M^II=Co, Ni). For each compound two phases, named a and β according to synthesis conditions, have been stabilized at room temperature, then characterized. The four crystal structures M(VO)₂(PO₄)₂ (a and β for M = Co, Ni) have been determined in monoclinic P2₁/c space group using X-ray single crystals diffraction data. Structure of the a phase is derived from the Lí(TiO)(PO₄) (orthorhombic Pnma) and LiNi_0.50(TiO)₂(PO₄)₂ (monoclinic P2₁/c) types, with cell parameters: a=6.310(1)Å, b=7.273(1)Å, c=7.432(1)Å, β=90.43(1)° for M=Co, and a = 6.297(2) A, b = 7.230(2) A, c = 7.421(2) A, β = 90.36(2)° for M = Ni. Structure of the β phase is derived from the Ni(TiO)₂(PO₄)₂-tyPe (monoclinic P2₁/c) with cell parameters: a=7.2742(2) Å, b=7.2802(2)Å, c = 7.4550(2) A β=120.171(2)° for M = Co, and a = 7.2691(2) A, b = 7.2366(2) A c = 7.4453(2) A, β = 120.231(2)° for M = Ni. All these structures consist of a three dimensional (3D) framework built up of infinite chains of tilted corner-sharing [VO₆] octahedra, cross-linked by corner-sharing [PO₄] tetrahedra. The M²⁺ ion (M = Co, Ni) is located in a triangular based antiprism which shares faces with two [VO₆] octahedra. Structural filiation is discussed based on a common structural unit, a sheet where divalent cations M²⁺ (M = Co, Ni) are inserted. A thermal study of the a ↔ β transition is also presented.
