Hydrothermal synthesis and crystal structure of [Ni(H[sub 2]O)[sub 4]][VO(PO[sub 4])][sub 2], a nickel(II) vanadyl(IV) phosphate
- NEC Research Institute, Princeton, NJ (United States)
- Syracuse Univ., Syracuse, NY (United States)
The new M[sup 2+]/V[sup 4+]/P/O phase [Ni([sub 2]O)[sub 4]][VO(PO[sub 4])][sub 2] was prepared by hydrothermal synthesis and characterized by X-ray crystallography and thermogravimetric analysis. Crystal data: tetragonal space group I4/mmm, a = 6.251(1)[angstrom], c = 13.338(3)[angstrom], V = 521.2(3)[angstrom][sup 3], Z = 2, D[sub calc] = 2.845 g/cm[sup 3]; structure solution and refinement based on 176 reflections with I[sub 0] [ge] 3[sigma](I[sub 0]) (MoK[alpha] radiation, [lambda] = 0.71073 [angstrom]) converged at R = 0.0564. The structure consists of (VO(PO[sub 4])) layers, constructed from VO[sub 5] square pyramids and PO[sub 4] tetrahedra, linked by NiO[sub 6] octahedra. The structure is distinct from that of Ni[sub 0.5][VO(PO[sub 4])][center dot]1.5H[sub 2]O, which exhibits a three-dimensional network structure with tunnels accommodating the aquo ligands.
