Abstract

(WSbO6)2O2 crystallizes in the orthorhombic Imma space group. The structure is three-dimensional and consists of four water molecules and one WSbO6 framework. In the WSbO6 framework, W is bonded to six O atoms to form WO6 octahedra that share corners with two equivalent WO6 octahedra and corners with four equivalent SbO6 octahedra. The corner-sharing octahedra tilt angles range from 35–40°. There is four shorter (1.93 Å) and two longer (1.95 Å) W–O bond length. Sb is bonded to six O atoms to form SbO6 octahedra that share corners with two equivalent SbO6 octahedra and corners with four equivalent WO6 octahedra. The corner-sharing octahedra tilt angles range from 40–47°. There is two shorter (1.97 Å) and four longer (2.00 Å) Sb–O bond length. There are three inequivalent O sites. In the first O site, O is bonded in a bent 150 degrees geometry to two equivalent W atoms. In the second O site, O is bonded in a bent 120 degrees geometry to two equivalent Sb atoms. In the third O site, O is bonded in a bent 150 degrees geometry to one W and one Sb atom.
