The material structure described by Li2GeN2 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a distorted trigonal planar geometry to two equivalent N(1) and two equivalent N(2) atoms. In the second Li site, Li(2) is bonded to two equivalent N(2) and three equivalent N(1) atoms to form distorted LiN5 trigonal bipyramids that share corners with six equivalent Ge(1)N4 tetrahedra, corners with two equivalent Li(2)N5 trigonal bipyramids, edges with two equivalent Ge(1)N4 tetrahedra, and edges with three equivalent Li(2)N5 trigonal bipyramids. 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 six equivalent Li(2)N5 trigonal bipyramids,  an edgeedge with one Ge(1)N4 tetrahedra, and edges with two equivalent Li(2)N5 trigonal bipyramids. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 7-coordinate geometry to two equivalent Li(1), three equivalent Li(2), and two equivalent Ge(1) atoms. In the second N site, N(2) is bonded in a 6-coordinate geometry to two equivalent Li(1), two equivalent Li(2), and two equivalent Ge(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
