The material structure described by Zn5(GeN3)2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a distorted trigonal planar geometry to one N(1) and two equivalent N(3) atoms. In the second Zn site, Zn(2) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent N(2) atoms. In the third Zn site, Zn(3) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted ZnN4 tetrahedra that share corners with four equivalent Ge(1)N4 tetrahedra. Ge(1) is bonded to one N(1), one N(2), and two equivalent N(3) atoms to form GeN4 tetrahedra that share corners with two equivalent Zn(3)N4 tetrahedra and  an edgeedge with one Ge(1)N4 tetrahedra. There are three inequivalent N sites. In the first N site, N(2) is bonded to one Zn(3), two equivalent Zn(2), and one Ge(1) atom to form corner-sharing NZn3Ge tetrahedra. In the second N site, N(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Zn(1) and two equivalent Ge(1) atoms. In the third N site, N(1) is bonded in a 5-coordinate geometry to one Zn(1), one Zn(3), two equivalent Zn(2), and one Ge(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
