The crystal structure described by Mg4GeN4 is Chalcostibite-like structured and crystallizes in the orthorhombic Pnna space group. There are three inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a trigonal planar geometry to one N(2) and two equivalent N(1) atoms. In the second Mg site, Mg(2) is bonded in a 4-coordinate geometry to four equivalent N(2) atoms. In the third Mg site, Mg(3) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent N(2) atoms. Ge(1) is bonded in a tetrahedral geometry to two equivalent N(1) and two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Mg(3), two equivalent Mg(1), and one Ge(1) atom to form NMg3Ge tetrahedra that share corners with four equivalent N(1)Mg3Ge tetrahedra, corners with four equivalent N(2)Mg4Ge trigonal bipyramids, and  an edgeedge with one N(2)Mg4Ge trigonal bipyramid. In the second N site, N(2) is bonded to one Mg(1), one Mg(3), two equivalent Mg(2), and one Ge(1) atom to form distorted NMg4Ge trigonal bipyramids that share corners with four equivalent N(1)Mg3Ge tetrahedra, corners with four equivalent N(2)Mg4Ge trigonal bipyramids,  an edgeedge with one N(1)Mg3Ge tetrahedra, and edges with two equivalent N(2)Mg4Ge trigonal bipyramids. is represented by the CIF card [CIF]
