Os3AuBi is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. Os(1) is bonded in a 2-coordinate geometry to two equivalent Au(1) and three equivalent Bi(1) atoms. There is one shorter (2.26 Å) and one longer (2.66 Å) Os(1)-Au(1) bond length. There is one shorter (3.19 Å) and two longer (3.49 Å) Os(1)-Bi(1) bond lengths. Au(1) is bonded to six equivalent Os(1) atoms to form corner-sharing AuOs6 octahedra. The corner-sharing octahedra are not tilted. Bi(1) is bonded in a 9-coordinate geometry to nine equivalent Os(1) atoms.
