Materials Data on Y4CdS7 by Materials Project
Abstract
Y4CdS7 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are four inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded to seven S2- atoms to form distorted YS7 pentagonal bipyramids that share corners with four YS6 octahedra, corners with four equivalent CdS6 octahedra, an edgeedge with one CdS6 octahedra, edges with three equivalent YS6 octahedra, edges with two equivalent YS7 pentagonal bipyramids, and faces with two equivalent YS7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 22–70°. There are a spread of Y–S bond distances ranging from 2.72–3.06 Å. In the second Y3+ site, Y3+ is bonded to seven S2- atoms to form distorted YS7 pentagonal bipyramids that share corners with two equivalent CdS6 octahedra, corners with six YS6 octahedra, edges with four YS6 octahedra, edges with two equivalent YS7 pentagonal bipyramids, and faces with two equivalent YS7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 21–69°. There are a spread of Y–S bond distances ranging from 2.71–3.00 Å. In the third Y3+ site, Y3+ is bonded to six S2- atoms to form YS6 octahedra that share a cornercorner with one YS6 octahedra, a cornercorner with one CdS6 octahedra, corners with fourmore »
