Materials Data on Sc4Co3Sb4 by Materials Project
Abstract
Sc4Co3Sb4 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are four inequivalent Sc2+ sites. In the first Sc2+ site, Sc2+ is bonded to six Sb3- atoms to form distorted ScSb6 octahedra that share corners with six CoSb4 tetrahedra, edges with six ScSb6 octahedra, edges with three CoSb4 tetrahedra, and faces with two equivalent CoSb4 tetrahedra. There are a spread of Sc–Sb bond distances ranging from 2.98–3.12 Å. In the second Sc2+ site, Sc2+ is bonded in a 6-coordinate geometry to six Sb3- atoms. There are a spread of Sc–Sb bond distances ranging from 2.97–3.23 Å. In the third Sc2+ site, Sc2+ is bonded to six Sb3- atoms to form ScSb6 octahedra that share corners with nine CoSb4 tetrahedra, edges with six ScSb6 octahedra, edges with three CoSb4 tetrahedra, and a faceface with one CoSb4 tetrahedra. There are a spread of Sc–Sb bond distances ranging from 2.96–3.09 Å. In the fourth Sc2+ site, Sc2+ is bonded in a 6-coordinate geometry to six Sb3- atoms. There are a spread of Sc–Sb bond distances ranging from 2.93–3.20 Å. There are three inequivalent Co+1.33+ sites. In the first Co+1.33+ site, Co+1.33+ is bonded to four Sb3- atoms to form CoSb4more »
