SiGeN2O crystallizes in the monoclinic Cm space group. 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 three equivalent Ge(1)N3O tetrahedra and corners with four equivalent Si(1)N3O tetrahedra. Si(1) is bonded to one N(1), two equivalent N(2), and one O(2) atom to form SiN3O tetrahedra that share corners with three equivalent Si(1)N3O tetrahedra and corners with four equivalent Ge(1)N3O tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to two equivalent Ge(1) and one Si(1) atom. In the second N site, N(2) is bonded in a trigonal planar geometry to one Ge(1) and two equivalent Si(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent Ge(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Si(1) atoms.
