The material structure described by Ge2N2O crystallizes in the monoclinic Pc space group. There are four inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one N(1), two equivalent N(2), and one O(1) atom to form GeN3O tetrahedra that share  a cornercorner with one Ge(4)N2O2 tetrahedra,  a cornercorner with one Ge(2)N4 tetrahedra, corners with two equivalent Ge(1)N3O tetrahedra, and corners with three equivalent Ge(3)N3O tetrahedra. In the second Ge site, Ge(2) is bonded to one N(1), one N(3), and two equivalent N(4) atoms to form GeN4 tetrahedra that share  a cornercorner with one Ge(1)N3O tetrahedra, corners with two equivalent Ge(3)N3O tetrahedra, corners with two equivalent Ge(2)N4 tetrahedra, and corners with three equivalent Ge(4)N2O2 tetrahedra. In the third Ge site, Ge(3) is bonded to one N(1), one N(2), one N(3), and one O(2) atom to form GeN3O tetrahedra that share corners with two equivalent Ge(4)N2O2 tetrahedra, corners with two equivalent Ge(2)N4 tetrahedra, and corners with three equivalent Ge(1)N3O tetrahedra. In the fourth Ge site, Ge(4) is bonded to one N(3), one N(4), one O(1), and one O(2) atom to form GeN2O2 tetrahedra that share  a cornercorner with one Ge(1)N3O tetrahedra, corners with two equivalent Ge(3)N3O tetrahedra, and corners with three equivalent Ge(2)N4 tetrahedra. There are four inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one Ge(1), one Ge(2), and one Ge(3) atom. In the second N site, N(2) is bonded in a trigonal non-coplanar geometry to one Ge(3) and two equivalent Ge(1) atoms. In the third N site, N(3) is bonded in a trigonal non-coplanar geometry to one Ge(2), one Ge(3), and one Ge(4) atom. In the fourth N site, N(4) is bonded in a trigonal planar geometry to one Ge(4) and two equivalent Ge(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Ge(1) and one Ge(4) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Ge(3) and one Ge(4) atom. is represented by the CIF card [CIF]
