Materials Data on K2Cu5TeS3O19 by Materials Project
Abstract
K2Cu5TeS3O19 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.61–2.90 Å. In the second K1+ site, K1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of K–O bond distances ranging from 2.78–3.20 Å. There are three inequivalent Cu+2.40+ sites. In the first Cu+2.40+ site, Cu+2.40+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with three SO4 tetrahedra and edges with three CuO6 octahedra. There are a spread of Cu–O bond distances ranging from 1.80–2.53 Å. In the second Cu+2.40+ site, Cu+2.40+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with three SO4 tetrahedra and edges with three CuO6 octahedra. There are a spread of Cu–O bond distances ranging from 1.79–2.62 Å. In the third Cu+2.40+ site, Cu+2.40+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with two equivalent SO4 tetrahedra and edges with four CuO6 octahedra.
