The material structure described by OsAsS crystallizes in the monoclinic P2_1/c space group. Os(1) is bonded in a 6-coordinate geometry to three equivalent As(1) and three equivalent S(1) atoms. As(1) is bonded to three equivalent Os(1) and one S(1) atom to form distorted AsOs3S tetrahedra that share corners with four equivalent As(1)Os3S tetrahedra, corners with nine equivalent S(1)AsOs3 tetrahedra, and  an edgeedge with one As(1)Os3S tetrahedra. S(1) is bonded to three equivalent Os(1) and one As(1) atom to form SAsOs3 tetrahedra that share corners with four equivalent S(1)AsOs3 tetrahedra, corners with nine equivalent As(1)Os3S tetrahedra, and  an edgeedge with one S(1)AsOs3 tetrahedra. is represented by the CIF file [CIF]
