Materials Data on V2CoO8 by Materials Project
V2CoO8 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. V is bonded to four O atoms to form VO4 tetrahedra that share corners with two equivalent CoO6 octahedra and corners with two equivalent VO4 tetrahedra. The corner-sharing octahedra tilt angles range from 14–27°. There are a spread of V–O bond distances ranging from 1.68–1.81 Å. Co is bonded to six O atoms to form CoO6 octahedra that share corners with four equivalent VO4 tetrahedra. There are a spread of Co–O bond distances ranging from 1.73–2.01 Å. There are five inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Co atom. In the second O site, O is bonded in a single-bond geometry to one Co atom. In the third O site, O is bonded in a linear geometry to one V and one Co atom. In the fourth O site, O is bonded in a bent 150 degrees geometry to one V and one Co atom. In the fifth O site, O is bonded in a bent 150 degrees geometry to two equivalent V atoms.
