Abstract
CsBi2CuS4 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. Cs1+ is bonded in a 7-coordinate geometry to seven S2- atoms. There are a spread of Cs–S bond distances ranging from 3.47–3.77 Å. Cu1+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners with two BiS6 octahedra, corners with two equivalent CuS4 tetrahedra, and edges with four BiS6 octahedra. The corner-sharing octahedra tilt angles range from 0–3°. There are a spread of Cu–S bond distances ranging from 2.28–2.72 Å. There are two inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded to six S2- atoms to form BiS6 octahedra that share corners with three equivalent BiS6 octahedra, a cornercorner with one CuS4 tetrahedra, edges with five BiS6 octahedra, and edges with two equivalent CuS4 tetrahedra. The corner-sharing octahedra tilt angles range from 3–25°. There are a spread of Bi–S bond distances ranging from 2.67–3.12 Å. In the second Bi3+ site, Bi3+ is bonded to six S2- atoms to form distorted BiS6 octahedra that share corners with three equivalent BiS6 octahedra, a cornercorner with one CuS4 tetrahedra, edges with five BiS6 octahedra, and edges with two equivalent CuS4 tetrahedra.
