The compound described by Cr5Ge3 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 7-coordinate geometry to one Cr(1), two equivalent Ge(2), and four equivalent Ge(1) atoms. In the second Cr site, Cr(2) is bonded in a 6-coordinate geometry to two equivalent Cr(2) and four equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 10-coordinate geometry to two equivalent Cr(2) and eight equivalent Cr(1) atoms. In the second Ge site, Ge(2) is bonded in a 10-coordinate geometry to eight equivalent Cr(1) and two equivalent Ge(2) atoms. is represented by the CIF file [CIF]
