Abstract
Ho(CuS)3 crystallizes in the trigonal P-3m1 space group. The structure is two-dimensional and consists of one Ho(CuS)3 sheet oriented in the (0, 0, 1) direction. Ho3+ is bonded to six S2- atoms to form HoS6 octahedra that share corners with nine CuS4 tetrahedra, edges with six equivalent HoS6 octahedra, and edges with six CuS4 tetrahedra. There are three shorter (2.72 Å) and three longer (2.84 Å) Ho–S bond lengths. There are three inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded to four equivalent S2- atoms to form CuS4 tetrahedra that share corners with six equivalent HoS6 octahedra, corners with six equivalent CuS4 tetrahedra, edges with three equivalent HoS6 octahedra, and edges with three equivalent CuS4 tetrahedra. The corner-sharing octahedra tilt angles range from 22–52°. There are three shorter (2.34 Å) and one longer (2.48 Å) Cu–S bond lengths. In the second Cu1+ site, Cu1+ is bonded in a trigonal planar geometry to three equivalent S2- atoms. All Cu–S bond lengths are 2.25 Å. In the third Cu1+ site, Cu1+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners with three equivalent HoS6 octahedra, corners with six equivalent CuS4 tetrahedra, and edges with threemore »
