Abstract

SrCu2GeS4 crystallizes in the trigonal P3_221 space group. The structure is three-dimensional. there are three inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Sr–S bond distances ranging from 3.11–3.22 Å.

The S–Cu bond length is 2.31 Å. In the fifth S2- site, S2- is bonded to two Sr2+, two Cu1+, and one Ge4+ atom to form a mixture of distorted edge and corner-sharing SSr2Cu2Ge trigonal bipyramids. In the sixth S2- site, S2- is bonded to two Sr2+, two Cu1+, and one Ge4+ atom to form a mixture of distorted edge and corner-sharing SSr2Cu2Ge trigonal bipyramids. The S–Cu bond length is 2.31 Å.
