Abstract
Yb2CrS4 crystallizes in the orthorhombic Pca2_1 space group. The structure is three-dimensional. there are four inequivalent Yb+2.50+ sites. In the first Yb+2.50+ site, Yb+2.50+ is bonded to six S2- atoms to form YbS6 octahedra that share a cornercorner with one CrS6 octahedra, corners with two equivalent YbS6 octahedra, corners with four YbS7 pentagonal bipyramids, an edgeedge with one YbS6 octahedra, edges with four CrS6 octahedra, and edges with three YbS7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 12–51°. There are a spread of Yb–S bond distances ranging from 2.64–2.81 Å. In the second Yb+2.50+ site, Yb+2.50+ is bonded to seven S2- atoms to form distorted YbS7 pentagonal bipyramids that share corners with four YbS6 octahedra, corners with four CrS6 octahedra, edges with three YbS6 octahedra, edges with three CrS6 octahedra, and faces with two equivalent YbS7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 12–72°. There are a spread of Yb–S bond distances ranging from 2.72–3.07 Å. In the third Yb+2.50+ site, Yb+2.50+ is bonded to six S2- atoms to form YbS6 octahedra that share a cornercorner with one CrS6 octahedra, corners with two equivalent YbS6 octahedra, corners with four YbS7 pentagonal bipyramids, an edgeedge with onemore »
