Abstract
Ho7Cu3Te12 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are seven inequivalent Ho3+ sites. In the first Ho3+ site, Ho3+ is bonded to six Te2- atoms to form HoTe6 octahedra that share a cornercorner with one HoTe6 octahedra, corners with three CuTe4 tetrahedra, edges with seven HoTe6 octahedra, and an edgeedge with one CuTe4 tetrahedra. The corner-sharing octahedral tilt angles are 1°. There are a spread of Ho–Te bond distances ranging from 3.05–3.09 Å. In the second Ho3+ site, Ho3+ is bonded to six Te2- atoms to form a mixture of edge and corner-sharing HoTe6 octahedra. The corner-sharing octahedral tilt angles are 1°. There are a spread of Ho–Te bond distances ranging from 3.04–3.07 Å. In the third Ho3+ site, Ho3+ is bonded to six Te2- atoms to form HoTe6 octahedra that share a cornercorner with one HoTe6 octahedra, corners with three CuTe4 tetrahedra, edges with seven HoTe6 octahedra, and edges with two CuTe4 tetrahedra. The corner-sharing octahedral tilt angles are 1°. There are a spread of Ho–Te bond distances ranging from 3.06–3.10 Å. In the fourth Ho3+ site, Ho3+ is bonded to six Te2- atoms to form HoTe6 octahedra that share a cornercorner with onemore »
