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.

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. The Cr(1)-Cr(1) bond length is 2.46 Å. Both Cr(1)-Ge(2) bond lengths are 2.59 Å. There are two shorter (2.46 Å) and two longer (2.66 Å) Cr(1)-Ge(1) bond lengths. 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. Both Cr(2)-Cr(2) bond lengths are 2.36 Å. All Cr(2)-Ge(1) bond lengths are 2.49 Å. There are two inequivalent Ge sites.
