Cr5(GeN3)2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a distorted rectangular see-saw-like geometry to one N(2), one N(3), and two equivalent N(1) atoms. In the second Cr site, Cr(2) is bonded in a 4-coordinate geometry to one N(1), one N(3), and two equivalent N(2) atoms. In the third Cr site, Cr(3) is bonded in a distorted trigonal pyramidal geometry to two equivalent N(1) and two equivalent N(3) atoms. Ge(1) is bonded in a water-like geometry to one N(2) and one N(3) atom. There are three inequivalent N sites. In the first N site, N(2) is bonded to one Cr(1), two equivalent Cr(2), and one Ge(1) atom to form distorted corner-sharing NCr3Ge trigonal pyramids. In the second N site, N(3) is bonded to one Cr(1), one Cr(2), one Cr(3), and one Ge(1) atom to form distorted corner-sharing NCr3Ge trigonal pyramids. In the third N site, N(1) is bonded in a rectangular see-saw-like geometry to one Cr(2), one Cr(3), and two equivalent Cr(1) atoms.

In the first Cr site, Cr(1) is bonded in a distorted rectangular see-saw-like geometry to one N(2), one N(3), and two equivalent N(1) atoms. The Cr(1)-N(2) bond length is 1.92 Å. The Cr(1)-N(3) bond length is 2.03 Å. There is one shorter (1.88 Å) and one longer (1.89 Å) Cr(1)-N(1) bond length. In the second Cr site, Cr(2) is bonded in a 4-coordinate geometry to one N(1), one N(3), and two equivalent N(2) atoms. The Cr(2)-N(1) bond length is 1.91 Å. The Cr(2)-N(3) bond length is 2.03 Å. There is one shorter (1.92 Å) and one longer (2.00 Å) Cr(2)-N(2) bond length. In the third Cr site, Cr(3) is bonded in a distorted trigonal pyramidal geometry to two equivalent N(1) and two equivalent N(3) atoms. Both Cr(3)-N(1) bond lengths are 1.88 Å. Both Cr(3)-N(3) bond lengths are 1.83 Å. Ge(1) is bonded in a water-like geometry to one N(2) and one N(3) atom. The Ge(1)-N(2) bond length is 1.92 Å. The Ge(1)-N(3) bond length is 1.98 Å.
