Mo5Ge3C crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Mo sites. In the first Mo site, Mo(2) is bonded in a 2-coordinate geometry to five equivalent Ge(1) and two equivalent C(1) atoms. In the second Mo site, Mo(1) is bonded in a 8-coordinate geometry to two equivalent Mo(1) and six equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Mo(1) and five equivalent Mo(2) atoms. C(1) is bonded to six equivalent Mo(2) atoms to form face-sharing CMo6 octahedra.
Mo5Ge3C crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Mo sites. In the first Mo site, Mo(2) is bonded in a 2-coordinate geometry to five equivalent Ge(1) and two equivalent C(1) atoms. There are a spread of Mo(2)-Ge(1) bond distances ranging from 2.62-2.98 Å. Both Mo(2)-C(1) bond lengths are 2.15 Å. In the second Mo site, Mo(1) is bonded in a 8-coordinate geometry to two equivalent Mo(1) and six equivalent Ge(1) atoms. Both Mo(1)-Mo(1) bond lengths are 2.67 Å. All Mo(1)-Ge(1) bond lengths are 2.64 Å. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Mo(1) and five equivalent Mo(2) atoms. C(1) is bonded to six equivalent Mo(2) atoms to form face-sharing CMo6 octahedra.
