The compound described by Ge2N2O is beta indium sulfide-derived structured and crystallizes in the tetragonal I4_1/amd space group. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to four equivalent N(1) and two equivalent O(1) atoms to form GeN4O2 octahedra that share corners with four equivalent Ge(3)N4 tetrahedra, edges with two equivalent Ge(1)N4O2 octahedra, and edges with four equivalent Ge(2)N4O2 octahedra. In the second Ge site, Ge(2) is bonded to one N(1), three equivalent N(2), and two equivalent O(1) atoms to form GeN4O2 octahedra that share corners with four equivalent Ge(3)N4 tetrahedra, edges with two equivalent Ge(1)N4O2 octahedra, and edges with four equivalent Ge(2)N4O2 octahedra. In the third Ge site, Ge(3) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing GeN4 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 Ge(3) and three equivalent Ge(2) atoms to form a mixture of distorted corner and edge-sharing NGe4 trigonal pyramids. In the second N site, N(1) is bonded in a distorted rectangular see-saw-like geometry to one Ge(2), one Ge(3), and two equivalent Ge(1) atoms. O(1) is bonded in a distorted trigonal non-coplanar geometry to one Ge(1) and two equivalent Ge(2) atoms. is represented by the CIF file [CIF]
