Abstract

Y3CoAlS7 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are three inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded to seven S2- atoms to form distorted YS7 pentagonal bipyramids that share a cornercorner with one CoS6 octahedra, corners with six YS7 pentagonal bipyramids, corners with two equivalent AlS4 tetrahedra, an edgeedge with one CoS6 octahedra, edges with four YS7 pentagonal bipyramids, an edgeedge with one AlS4 tetrahedra, and a faceface with one CoS6 octahedra. The corner-sharing octahedral tilt angles are 23°. There are a spread of Y–S bond distances ranging from 2.75–2.96 Å. In the second Y3+ site, Y3+ is bonded to seven S2- atoms to form distorted YS7 pentagonal bipyramids that share a cornercorner with one CoS6 octahedra, corners with six YS7 pentagonal bipyramids, corners with two equivalent AlS4 tetrahedra, an edgeedge with one CoS6 octahedra, edges with four YS7 pentagonal bipyramids, an edgeedge with one AlS4 tetrahedra, and a faceface with one CoS6 octahedra. The corner-sharing octahedral tilt angles are 22°. There are a spread of Y–S bond distances ranging from 2.75–2.96 Å.
