Abstract

CsHo2Cu3Se5 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Cs1+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Cs–Se bond distances ranging from 3.50–3.66 Å. Ho3+ is bonded to six Se2- atoms to form HoSe6 octahedra that share a cornercorner with one HoSe6 octahedra, corners with four equivalent CuSe4 tetrahedra, edges with four equivalent HoSe6 octahedra, and edges with five CuSe4 tetrahedra. The corner-sharing octahedral tilt angles are 27°. There are a spread of Ho–Se bond distances ranging from 2.82–2.92 Å. There are two inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded to four Se2- atoms to form CuSe4 tetrahedra that share corners with six CuSe4 tetrahedra and edges with four equivalent HoSe6 octahedra. There are two shorter (2.39 Å) and two longer (2.78 Å) Cu–Se bond lengths. In the second Cu1+ site, Cu1+ is bonded to four Se2- atoms to form CuSe4 tetrahedra that share corners with four equivalent HoSe6 octahedra, corners with four CuSe4 tetrahedra, edges with three equivalent HoSe6 octahedra, and an edgeedge with one CuSe4 tetrahedra. The corner-sharing octahedra tilt angles range from 15–60°. There are three shorter (2.52 Å) and one longermore »« less
