The structure described by ZnGeN2 is Enargite-like structured and crystallizes in the monoclinic P2_1/c space group. Zn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form ZnN4 tetrahedra that share corners with two equivalent Zn(1)N4 tetrahedra, corners with eight equivalent Ge(1)N4 tetrahedra, and  an edgeedge with one Zn(1)N4 tetrahedra. Ge(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form GeN4 tetrahedra that share corners with two equivalent Ge(1)N4 tetrahedra, corners with eight equivalent Zn(1)N4 tetrahedra, and  an edgeedge with one Ge(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Zn(1) and two equivalent Ge(1) atoms to form a mixture of edge and corner-sharing NZn2Ge2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Zn(1) and two equivalent Ge(1) atoms to form a mixture of edge and corner-sharing NZn2Ge2 tetrahedra. is represented by the CIF card [CIF]
