N2 - Two new phosphates, CaM2(PO4)2(HPO4) (M = FeIII or VIII), have been synthesised hydrothermally at 400°C and characterized by single-crystal X-ray diffraction. Crystal data: CaFe2(PO4)2(HPO4), monoclinic, space group P21/n, a = 6.3663(6), b = 19.752(2), c = 6.5030(8) Å, β = 91.626(9)°, Z = 4 and R = 0.0240; CaV2(PO4)2(HPO4), as above except a = 6.359(2), b = 19.973(2), c = 6.4744(4) Å, β = 91.51(1)°and R = 0.0390. The two compounds are isostructural. The framework consists of corner-sharing PO4 tetrahedra, HPO4 groups and dimers of edge-sharing MO6 octahedra forming M2O10 units. The structure of CaFe2(PO4)2(HPO4) was further defined by thermogravimetric and Mössbauer studies.
