The crystal structure described by LiGe2N3 is Enargite-like structured and crystallizes in the orthorhombic Cmc2_1 space group. Li(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form LiN4 tetrahedra that share corners with two equivalent Li(1)N4 tetrahedra and corners with ten equivalent Ge(1)N4 tetrahedra. Ge(1) is bonded to one N(2) and three equivalent N(1) atoms to form GeN4 tetrahedra that share corners with five equivalent Li(1)N4 tetrahedra and corners with seven equivalent Ge(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(2) is bonded to two equivalent Li(1) and two equivalent Ge(1) atoms to form NLi2Ge2 tetrahedra that share corners with two equivalent N(2)Li2Ge2 tetrahedra and corners with ten equivalent N(1)LiGe3 tetrahedra. In the second N site, N(1) is bonded to one Li(1) and three equivalent Ge(1) atoms to form NLiGe3 tetrahedra that share corners with five equivalent N(2)Li2Ge2 tetrahedra and corners with seven equivalent N(1)LiGe3 tetrahedra. is represented by the CIF file [CIF]
