Materials Data on Cr5Ge3 by Materials Project
Cr5Ge3 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent Cr sites. In the first Cr site, Cr is bonded in a 7-coordinate geometry to one Cr and six Ge atoms. The Cr–Cr bond length is 2.46 Å. There are a spread of Cr–Ge bond distances ranging from 2.46–2.66 Å. In the second Cr site, Cr is bonded in a 6-coordinate geometry to two equivalent Cr and four equivalent Ge atoms. Both Cr–Cr bond lengths are 2.36 Å. All Cr–Ge bond lengths are 2.49 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 10-coordinate geometry to ten Cr atoms. In the second Ge site, Ge is bonded in a 10-coordinate geometry to eight equivalent Cr and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.36 Å.
