Abstract

Cu2TiTe3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Ti4+ is bonded to six Te2- atoms to form distorted TiTe6 octahedra that share corners with nine CuTe4 tetrahedra, edges with four equivalent TiTe6 octahedra, edges with two equivalent CuTe4 tetrahedra, and a faceface with one CuTe4 tetrahedra. There are a spread of Ti–Te bond distances ranging from 2.66–3.03 Å. There are two inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded to four Te2- atoms to form CuTe4 tetrahedra that share corners with seven equivalent TiTe6 octahedra, corners with four CuTe4 tetrahedra, edges with two equivalent CuTe4 tetrahedra, and a faceface with one TiTe6 octahedra. The corner-sharing octahedra tilt angles range from 52–62°. There are a spread of Cu–Te bond distances ranging from 2.61–2.68 Å. In the second Cu1+ site, Cu1+ is bonded to four Te2- atoms to form CuTe4 tetrahedra that share corners with two equivalent TiTe6 octahedra, corners with four CuTe4 tetrahedra, edges with two equivalent TiTe6 octahedra, and an edgeedge with one CuTe4 tetrahedra. The corner-sharing octahedral tilt angles are 71°. There are a spread of Cu–Te bond distances ranging from 2.57–2.67 Å. There are three inequivalent Te2- sites. In the firstmore »« less
