The crystal structure described by U(SiO)2 crystallizes in the tetragonal I4_1/amd space group. The structure is zero-dimensional and consists of eight U(SiO)2 clusters. U(1) is bonded in a linear geometry to two equivalent O(1) atoms. Si(1) is bonded in a single-bond geometry to one O(1) atom. O(1) is bonded in a bent 150 degrees geometry to one U(1) and one Si(1) atom. is represented by the CIF file [CIF]
