Zn4GeN4 is Chalcostibite-like structured and crystallizes in the orthorhombic Pnna space group. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a trigonal planar geometry to one N(2) and two equivalent N(1) atoms. In the second Zn site, Zn(2) is bonded in a 4-coordinate geometry to four equivalent N(2) atoms. In the third Zn site, Zn(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 Zn(3), two equivalent Zn(1), and one Ge(1) atom to form NZn3Ge tetrahedra that share corners with four equivalent N(1)Zn3Ge tetrahedra, corners with four equivalent N(2)Zn4Ge trigonal bipyramids, and  an edgeedge with one N(2)Zn4Ge trigonal bipyramid. In the second N site, N(2) is bonded to one Zn(1), one Zn(3), two equivalent Zn(2), and one Ge(1) atom to form distorted NZn4Ge trigonal bipyramids that share corners with four equivalent N(1)Zn3Ge tetrahedra, corners with four equivalent N(2)Zn4Ge trigonal bipyramids,  an edgeedge with one N(1)Zn3Ge tetrahedra, and edges with two equivalent N(2)Zn4Ge trigonal bipyramids.

In the first Zn site, Zn(1) is bonded in a trigonal planar geometry to one N(2) and two equivalent N(1) atoms. The Zn(1)-N(2) bond length is 2.10 Å. There is one shorter (1.96 Å) and one longer (1.98 Å) Zn(1)-N(1) bond length. In the second Zn site, Zn(2) is bonded in a 4-coordinate geometry to four equivalent N(2) atoms. There are two shorter (1.99 Å) and two longer (2.41 Å) Zn(2)-N(2) bond lengths. In the third Zn site, Zn(3) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent N(2) atoms. Both Zn(3)-N(1) bond lengths are 2.02 Å. Both Zn(3)-N(2) bond lengths are 2.19 Å. Ge(1) is bonded in a tetrahedral geometry to two equivalent N(1) and two equivalent N(2) atoms. Both Ge(1)-N(1) bond lengths are 1.88 Å. Both Ge(1)-N(2) bond lengths are 1.91 Å. There are two inequivalent N sites.
