Sn2N2O is beta indium sulfide-derived structured and crystallizes in the tetragonal I4_1/amd space group. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to four equivalent N(1) and two equivalent O(1) atoms to form SnN4O2 octahedra that share corners with four equivalent Sn(3)N4 tetrahedra, edges with two equivalent Sn(1)N4O2 octahedra, and edges with four equivalent Sn(2)N4O2 octahedra. In the second Sn site, Sn(2) is bonded to one N(1), three equivalent N(2), and two equivalent O(1) atoms to form SnN4O2 octahedra that share corners with four equivalent Sn(3)N4 tetrahedra, edges with two equivalent Sn(1)N4O2 octahedra, and edges with four equivalent Sn(2)N4O2 octahedra. In the third Sn site, Sn(3) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing SnN4 tetrahedra. The corner-sharing octahedral tilt angles range from 57-59°. There are two inequivalent N sites. In the first N site, N(2) is bonded to one Sn(3) and three equivalent Sn(2) atoms to form a mixture of distorted corner and edge-sharing NSn4 trigonal pyramids. In the second N site, N(1) is bonded in a distorted rectangular see-saw-like geometry to one Sn(2), one Sn(3), and two equivalent Sn(1) atoms. O(1) is bonded in a distorted trigonal non-coplanar geometry to one Sn(1) and two equivalent Sn(2) atoms.

All Sn(1)-N(1) bond lengths are 2.21 Å. Both Sn(1)-O(1) bond lengths are 2.12 Å. In the second Sn site, Sn(2) is bonded to one N(1), three equivalent N(2), and two equivalent O(1) atoms to form SnN4O2 octahedra that share corners with four equivalent Sn(3)N4 tetrahedra, edges with two equivalent Sn(1)N4O2 octahedra, and edges with four equivalent Sn(2)N4O2 octahedra. The Sn(2)-N(1) bond length is 2.22 Å. There is one shorter (2.20 Å) and two longer (2.21 Å) Sn(2)-N(2) bond lengths. Both Sn(2)-O(1) bond lengths are 2.13 Å. In the third Sn site, Sn(3) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing SnN4 tetrahedra. The corner-sharing octahedral tilt angles range from 57-59°. Both Sn(3)-N(1) bond lengths are 2.12 Å. Both Sn(3)-N(2) bond lengths are 2.10 Å. There are two inequivalent N sites. In the first N site, N(2) is bonded to one Sn(3) and three equivalent Sn(2) atoms to form a mixture of distorted corner and edge-sharing NSn4 trigonal pyramids. In the second N site, N(1) is bonded in a distorted rectangular see-saw-like geometry to one Sn(2), one Sn(3), and two equivalent Sn(1) atoms.
