Materials Data on V2Re2O11 by Materials Project

V2Re2O11 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. there are two inequivalent V5+ sites. In the first V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with three equivalent ReO6 octahedra and a cornercorner with one VO5 trigonal bipyramid. The corner-sharing octahedra tilt angles range from 15–30°. There are a spread of V–O bond distances ranging from 1.67–1.81 Å. In the second V5+ site, V5+ is bonded to five O2- atoms to form VO5 trigonal bipyramids that share corners with two equivalent ReO6 octahedra, a cornercorner with one VO4 tetrahedra, and corners with two equivalent ReO4 tetrahedra. The corner-sharing octahedra tilt angles range from 13–24°. There are a spread of V–O bond distances ranging from 1.88–2.00 Å. There are two inequivalent Re6+ sites. In the first Re6+ site, Re6+ is bonded to four O2- atoms to form ReO4 tetrahedra that share corners with two equivalent VO5 trigonal bipyramids. There are a spread of Re–O bond distances ranging from 1.72–1.78 Å. In the second Re6+ site, Re6+ is bonded to six O2- atoms to form distorted ReO6 octahedra that share corners with three equivalent VO4 tetrahedra and corners with two equivalent VO5 trigonal bipyramids. There are a spread of Re–O bond distances ranging from 1.74–2.32 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Re6+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two V5+ atoms. In the third O2- site, O2- is bonded in a single-bond geometry to one Re6+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one V5+ and one Re6+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one Re6+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one V5+ and one Re6+ atom. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to one V5+ and one Re6+ atom. In the eighth O2- site, O2- is bonded in a linear geometry to one V5+ and one Re6+ atom. In the ninth O2- site, O2- is bonded in a bent 150 degrees geometry to one V5+ and one Re6+ atom.
