Materials Data on CsGe by Materials Project
GeCs crystallizes in the cubic P-43n space group. The structure is three-dimensional. there are two inequivalent Cs sites. In the first Cs site, Cs is bonded in a 6-coordinate geometry to six Ge atoms. There are three shorter (3.77 Å) and three longer (4.03 Å) Cs–Ge bond lengths. In the second Cs site, Cs is bonded in a 6-coordinate geometry to six Ge atoms. There are a spread of Cs–Ge bond distances ranging from 3.64–4.04 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to six Cs and three equivalent Ge atoms. All Ge–Ge bond lengths are 2.61 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to six Cs and three equivalent Ge atoms. There are two shorter (2.60 Å) and one longer (2.63 Å) Ge–Ge bond lengths.
