Title: Materials Data on BaCu2GeS4 by Materials Project

Abstract

BaCu2GeS4 crystallizes in the trigonal P3_121 space group. The structure is three-dimensional. Ba2+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Ba–S bond distances ranging from 3.18–3.27 Å. Cu1+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners with four equivalent CuS4 tetrahedra and corners with four equivalent GeS4 tetrahedra. There are a spread of Cu–S bond distances ranging from 2.34–2.41 Å. Ge4+ is bonded to four S2- atoms to form GeS4 tetrahedra that share corners with eight equivalent CuS4 tetrahedra. There are two shorter (2.26 Å) and two longer (2.27 Å) Ge–S bond lengths. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded to two equivalent Ba2+, two equivalent Cu1+, and one Ge4+ atom to form a mixture of distorted corner and edge-sharing SBa2Cu2Ge trigonal bipyramids. In the second S2- site, S2- is bonded in a 5-coordinate geometry to two equivalent Ba2+, two equivalent Cu1+, and one Ge4+ atom.
