Cd5(GeN3)2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent N(3) atoms. In the second Cd site, Cd(2) is bonded in a T-shaped geometry to one N(1) and two equivalent N(2) atoms. In the third Cd site, Cd(3) is bonded in a bent 150 degrees geometry to two equivalent N(2) atoms. Ge(1) is bonded to one N(1), one N(2), and two equivalent N(3) atoms to form edge-sharing GeN4 tetrahedra. There are three inequivalent N sites. In the first N site, N(2) is bonded to one Cd(3), two equivalent Cd(2), and one Ge(1) atom to form distorted NCd3Ge tetrahedra that share corners with three equivalent N(2)Cd3Ge tetrahedra, corners with two equivalent N(3)Cd2Ge2 trigonal pyramids, and corners with three equivalent N(1)Cd3Ge trigonal pyramids. In the second N site, N(3) is bonded to two equivalent Cd(1) and two equivalent Ge(1) atoms to form distorted NCd2Ge2 trigonal pyramids that share corners with two equivalent N(2)Cd3Ge tetrahedra, corners with four equivalent N(1)Cd3Ge trigonal pyramids,  an edgeedge with one N(1)Cd3Ge trigonal pyramid, and edges with two equivalent N(3)Cd2Ge2 trigonal pyramids. In the third N site, N(1) is bonded to one Cd(2), two equivalent Cd(1), and one Ge(1) atom to form NCd3Ge trigonal pyramids that share corners with three equivalent N(2)Cd3Ge tetrahedra, corners with four equivalent N(3)Cd2Ge2 trigonal pyramids,  an edgeedge with one N(3)Cd2Ge2 trigonal pyramid, and  an edgeedge with one N(1)Cd3Ge trigonal pyramid.
Cd5(GeN3)2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent N(3) atoms. There is one shorter (2.25 Å) and one longer (2.45 Å) Cd(1)-N(1) bond length. There is one shorter (2.22 Å) and one longer (2.51 Å) Cd(1)-N(3) bond length. In the second Cd site, Cd(2) is bonded in a T-shaped geometry to one N(1) and two equivalent N(2) atoms. The Cd(2)-N(1) bond length is 2.17 Å. There is one shorter (2.16 Å) and one longer (2.34 Å) Cd(2)-N(2) bond length. In the third Cd site, Cd(3) is bonded in a bent 150 degrees geometry to two equivalent N(2) atoms. Both Cd(3)-N(2) bond lengths are 2.12 Å. Ge(1) is bonded to one N(1), one N(2), and two equivalent N(3) atoms to form edge-sharing GeN4 tetrahedra. The Ge(1)-N(1) bond length is 1.86 Å. The Ge(1)-N(2) bond length is 1.86 Å. There is one shorter (1.90 Å) and one longer (1.94 Å) Ge(1)-N(3) bond length. There are three inequivalent N sites. In the first N site, N(2) is bonded to one Cd(3), two equivalent Cd(2), and one Ge(1) atom to form distorted NCd3Ge tetrahedra that share corners with three equivalent N(2)Cd3Ge tetrahedra, corners with two equivalent N(3)Cd2Ge2 trigonal pyramids, and corners with three equivalent N(1)Cd3Ge trigonal pyramids.
