OsAu3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Os(1) is bonded to twelve equivalent Au(1) atoms to form OsAu12 cuboctahedra that share corners with twelve equivalent Os(1)Au12 cuboctahedra, edges with twenty-four equivalent Au(1)Os4Au8 cuboctahedra, faces with six equivalent Os(1)Au12 cuboctahedra, and faces with twelve equivalent Au(1)Os4Au8 cuboctahedra. Au(1) is bonded to four equivalent Os(1) and eight equivalent Au(1) atoms to form AuOs4Au8 cuboctahedra that share corners with twelve equivalent Au(1)Os4Au8 cuboctahedra, edges with eight equivalent Os(1)Au12 cuboctahedra, edges with sixteen equivalent Au(1)Os4Au8 cuboctahedra, faces with four equivalent Os(1)Au12 cuboctahedra, and faces with fourteen equivalent Au(1)Os4Au8 cuboctahedra.
