OsSbS crystallizes in the monoclinic P2_1/c space group. Os(1) is bonded in a 6-coordinate geometry to three equivalent Sb(1) and three equivalent S(1) atoms. Sb(1) is bonded to three equivalent Os(1) and one S(1) atom to form distorted SbOs3S tetrahedra that share corners with four equivalent Sb(1)Os3S tetrahedra, corners with nine equivalent S(1)SbOs3 tetrahedra, and  an edgeedge with one Sb(1)Os3S tetrahedra. S(1) is bonded to three equivalent Os(1) and one Sb(1) atom to form SSbOs3 tetrahedra that share corners with four equivalent S(1)SbOs3 tetrahedra, corners with nine equivalent Sb(1)Os3S tetrahedra, and  an edgeedge with one S(1)SbOs3 tetrahedra.
OsSbS crystallizes in the monoclinic P2_1/c space group. Os(1) is bonded in a 6-coordinate geometry to three equivalent Sb(1) and three equivalent S(1) atoms. There are a spread of Os(1)-Sb(1) bond distances ranging from 2.65-2.70 Å. There is one shorter (2.35 Å) and two longer (2.39 Å) Os(1)-S(1) bond lengths. Sb(1) is bonded to three equivalent Os(1) and one S(1) atom to form distorted SbOs3S tetrahedra that share corners with four equivalent Sb(1)Os3S tetrahedra, corners with nine equivalent S(1)SbOs3 tetrahedra, and  an edgeedge with one Sb(1)Os3S tetrahedra. The Sb(1)-S(1) bond length is 2.63 Å. S(1) is bonded to three equivalent Os(1) and one Sb(1) atom to form SSbOs3 tetrahedra that share corners with four equivalent S(1)SbOs3 tetrahedra, corners with nine equivalent Sb(1)Os3S tetrahedra, and  an edgeedge with one S(1)SbOs3 tetrahedra.
