SO crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two sulfur monoxide molecules. S(1) is bonded in a distorted single-bond geometry to one O(1) atom. The S(1)-O(1) bond length is 1.27 Å. O(1) is bonded in a distorted single-bond geometry to one S(1) atom.
