Sn3N4 is Hausmannite structured and crystallizes in the cubic Fd-3m space group. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to six equivalent N(1) atoms to form SnN6 octahedra that share corners with six equivalent Sn(2)N4 tetrahedra and edges with six equivalent Sn(1)N6 octahedra. In the second Sn site, Sn(2) is bonded to four equivalent N(1) atoms to form corner-sharing SnN4 tetrahedra. The corner-sharing octahedral tilt angles are 58°. N(1) is bonded to one Sn(2) and three equivalent Sn(1) atoms to form a mixture of distorted corner and edge-sharing NSn4 trigonal pyramids.

In the first Sn site, Sn(1) is bonded to six equivalent N(1) atoms to form SnN6 octahedra that share corners with six equivalent Sn(2)N4 tetrahedra and edges with six equivalent Sn(1)N6 octahedra. All Sn(1)-N(1) bond lengths are 2.18 Å. In the second Sn site, Sn(2) is bonded to four equivalent N(1) atoms to form corner-sharing SnN4 tetrahedra. The corner-sharing octahedral tilt angles are 58°. All Sn(2)-N(1) bond lengths are 2.10 Å. N(1) is bonded to one Sn(2) and three equivalent Sn(1) atoms to form a mixture of distorted corner and edge-sharing NSn4 trigonal pyramids.
