Abstract
Y7Cu3Te12 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are seven inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded to six Te2- atoms to form YTe6 octahedra that share a cornercorner with one YTe6 octahedra, corners with three CuTe4 tetrahedra, edges with seven YTe6 octahedra, and an edgeedge with one CuTe4 tetrahedra. The corner-sharing octahedral tilt angles are 1°. There are a spread of Y–Te bond distances ranging from 3.04–3.12 Å. In the second Y3+ site, Y3+ is bonded to six Te2- atoms to form a mixture of edge and corner-sharing YTe6 octahedra. The corner-sharing octahedral tilt angles are 1°. There are a spread of Y–Te bond distances ranging from 3.05–3.10 Å. In the third Y3+ site, Y3+ is bonded to six Te2- atoms to form YTe6 octahedra that share a cornercorner with one YTe6 octahedra, corners with three CuTe4 tetrahedra, edges with seven YTe6 octahedra, and edges with two CuTe4 tetrahedra. The corner-sharing octahedral tilt angles are 1°. There are a spread of Y–Te bond distances ranging from 3.06–3.12 Å. In the fourth Y3+ site, Y3+ is bonded to six Te2- atoms to form YTe6 octahedra that share a cornercorner with onemore »
