Title: Materials Data on Cd(CoO2)2 by Materials Project

Abstract

Cd(CoO2)2 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are eight inequivalent Co3+ sites. In the first Co3+ site, Co3+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with two equivalent CdO6 pentagonal pyramids, edges with six CoO6 octahedra, and a faceface with one CdO6 pentagonal pyramid. There are a spread of Co–O bond distances ranging from 1.89–2.27 Å. In the second Co3+ site, Co3+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with three CdO6 pentagonal pyramids, edges with six CoO6 octahedra, and an edgeedge with one CdO6 pentagonal pyramid. There are a spread of Co–O bond distances ranging from 1.89–2.22 Å. In the third Co3+ site, Co3+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with two equivalent CdO6 pentagonal pyramids, edges with six CoO6 octahedra, and a faceface with one CdO6 pentagonal pyramid. There are a spread of Co–O bond distances ranging from 1.90–2.20 Å. In the fourth Co3+ site, Co3+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with three CdO6 pentagonal pyramids, edges with six CoO6 octahedra, and an edgeedge withmore » one CdO6 pentagonal pyramid.
