Ge3N4 is Hausmannite structured and crystallizes in the cubic Fd-3m space group. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to six equivalent N(1) atoms to form GeN6 octahedra that share corners with six equivalent Ge(2)N4 tetrahedra and edges with six equivalent Ge(1)N6 octahedra. In the second Ge site, Ge(2) is bonded to four equivalent N(1) atoms to form corner-sharing GeN4 tetrahedra. The corner-sharing octahedral tilt angles are 57°. N(1) is bonded to one Ge(2) and three equivalent Ge(1) atoms to form a mixture of distorted edge and corner-sharing NGe4 trigonal pyramids.

In the first Ge site, Ge(1) is bonded to six equivalent N(1) atoms to form GeN6 octahedra that share corners with six equivalent Ge(2)N4 tetrahedra and edges with six equivalent Ge(1)N6 octahedra. All Ge(1)-N(1) bond lengths are 2.01 Å. In the second Ge site, Ge(2) is bonded to four equivalent N(1) atoms to form corner-sharing GeN4 tetrahedra. The corner-sharing octahedral tilt angles are 57°. All Ge(2)-N(1) bond lengths are 1.92 Å. N(1) is bonded to one Ge(2) and three equivalent Ge(1) atoms to form a mixture of distorted edge and corner-sharing NGe4 trigonal pyramids.
