Abstract
Y2(CuS2)3 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are two inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded to six S2- atoms to form YS6 octahedra that share corners with two equivalent YS6 octahedra, corners with six CuS4 tetrahedra, edges with two equivalent YS6 octahedra, and edges with three CuS4 tetrahedra. The corner-sharing octahedral tilt angles are 54°. There are a spread of Y–S bond distances ranging from 2.64–2.90 Å. In the second Y3+ site, Y3+ is bonded to six S2- atoms to form YS6 octahedra that share corners with two equivalent YS6 octahedra, corners with six CuS4 tetrahedra, edges with two equivalent YS6 octahedra, and edges with three CuS4 tetrahedra. The corner-sharing octahedral tilt angles are 55°. There are a spread of Y–S bond distances ranging from 2.64–2.89 Å. There are three inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners with four YS6 octahedra, corners with two CuS4 tetrahedra, edges with two YS6 octahedra, and edges with two CuS4 tetrahedra. The corner-sharing octahedra tilt angles range from 19–57°. There are a spread of Cu–S bond distances rangingmore »
