The material described by Ge2N2O crystallizes in the monoclinic C2/m space group. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one N(2), two equivalent N(1), and one O(1) atom to form GeN3O tetrahedra that share corners with seven equivalent Ge(2)N4O2 octahedra and corners with two equivalent Ge(1)N3O tetrahedra. The corner-sharing octahedral tilt angles range from 55-63°. 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 seven equivalent Ge(1)N3O tetrahedra and edges with four equivalent Ge(2)N4O2 octahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one Ge(2) and two equivalent Ge(1) atoms. In the second N site, N(2) is bonded to one Ge(1) and three equivalent Ge(2) atoms to form a mixture of distorted corner and edge-sharing NGe4 tetrahedra. O(1) is bonded in a distorted trigonal planar geometry to one Ge(1) and two equivalent Ge(2) atoms. is represented by the CIF file [CIF]
