Title: Materials Data on CaVO2 by Materials Project

Abstract

CaVO2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded to five O2- atoms to form distorted CaO5 trigonal bipyramids that share corners with six VO5 trigonal bipyramids, an edgeedge with one VO5 trigonal bipyramid, edges with two equivalent CaO5 trigonal bipyramids, and a faceface with one VO5 trigonal bipyramid. There are a spread of Ca–O bond distances ranging from 2.29–2.36 Å. In the second Ca2+ site, Ca2+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Ca–O bond distances ranging from 2.20–2.32 Å. There are two inequivalent V2+ sites. In the first V2+ site, V2+ is bonded to five O2- atoms to form distorted VO5 trigonal bipyramids that share corners with four equivalent CaO5 trigonal bipyramids, corners with four equivalent VO5 trigonal bipyramids, an edgeedge with one CaO5 trigonal bipyramid, and edges with two equivalent VO5 trigonal bipyramids. There are a spread of V–O bond distances ranging from 2.08–2.28 Å. In the second V2+ site, V2+ is bonded to five O2- atoms to form distorted VO5 trigonal bipyramids that share corners with two equivalent CaO5 trigonalmore » bipyramids, corners with four equivalent VO5 trigonal bipyramids, edges with two equivalent VO5 trigonal bipyramids, and a faceface with one CaO5 trigonal bipyramid. There are a spread of V–O bond distances ranging from 2.07–2.23 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to one Ca2+ and three V2+ atoms to form distorted OCaV3 tetrahedra that share corners with two equivalent OCaV3 tetrahedra, corners with eight OCa2V3 trigonal bipyramids, and edges with three OCa3V2 trigonal bipyramids. In the second O2- site, O2- is bonded to two equivalent Ca2+ and three V2+ atoms to form OCa2V3 trigonal bipyramids that share corners with four equivalent OCaV3 tetrahedra, corners with four equivalent OCa3V2 trigonal bipyramids, and edges with five OCa2V3 trigonal bipyramids. In the third O2- site, O2- is bonded to three Ca2+ and two equivalent V2+ atoms to form distorted OCa3V2 trigonal bipyramids that share corners with four equivalent OCaV3 tetrahedra, corners with three equivalent OCa3V2 trigonal bipyramids, an edgeedge with one OCaV3 tetrahedra, and edges with five OCa2V3 trigonal bipyramids. In the fourth O2- site, O2- is bonded to three Ca2+ and two equivalent V2+ atoms to form distorted OCa3V2 trigonal bipyramids that share corners with seven OCa2V3 trigonal bipyramids, edges with two equivalent OCaV3 tetrahedra, and edges with four OCa2V3 trigonal bipyramids.« less
