Title: Materials Data on V2Cd(P2O7)2 by Materials Project

Abstract

V2Cd(P2O7)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent V3+ sites. In the first V3+ site, V3+ is bonded to six O2- atoms to form VO6 octahedra that share corners with six PO4 tetrahedra and edges with two equivalent CdO6 octahedra. There are a spread of V–O bond distances ranging from 1.96–2.11 Å. In the second V3+ site, V3+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent CdO6 octahedra and corners with six PO4 tetrahedra. The corner-sharing octahedral tilt angles are 61°. There are a spread of V–O bond distances ranging from 1.96–2.22 Å. Cd2+ is bonded to six O2- atoms to form distorted CdO6 octahedra that share corners with two equivalent VO6 octahedra, corners with six PO4 tetrahedra, and edges with two equivalent VO6 octahedra. The corner-sharing octahedral tilt angles are 61°. There are a spread of Cd–O bond distances ranging from 2.33–2.67 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one CdO6 octahedra, corners with three VO6 octahedra, and a cornercorner with onemore » PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 24–59°. There are a spread of P–O bond distances ranging from 1.50–1.59 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent CdO6 octahedra, corners with three VO6 octahedra, and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 31–60°. There are a spread of P–O bond distances ranging from 1.51–1.61 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two P5+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one V3+, one Cd2+, and one P5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one V3+, one Cd2+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one V3+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one V3+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to one V3+, one Cd2+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to one V3+ and one P5+ atom.« less
