Mo5Ge3 crystallizes in the orthorhombic Cmcm space group. There are three inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 8-coordinate geometry to two equivalent Mo(1), two equivalent Ge(1), and four equivalent Ge(2) atoms. In the second Mo site, Mo(2) is bonded in a 5-coordinate geometry to two equivalent Ge(2) and three equivalent Ge(1) atoms. In the third Mo site, Mo(3) is bonded in a 5-coordinate geometry to one Ge(1) and four equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Mo(3), three equivalent Mo(2), and four equivalent Mo(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to one Mo(2), four equivalent Mo(1), and four equivalent Mo(3) atoms.
Mo5Ge3 crystallizes in the orthorhombic Cmcm space group. There are three inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 8-coordinate geometry to two equivalent Mo(1), two equivalent Ge(1), and four equivalent Ge(2) atoms. Both Mo(1)-Mo(1) bond lengths are 2.56 Å. Both Mo(1)-Ge(1) bond lengths are 2.64 Å. There are two shorter (2.63 Å) and two longer (2.64 Å) Mo(1)-Ge(2) bond lengths. In the second Mo site, Mo(2) is bonded in a 5-coordinate geometry to two equivalent Ge(2) and three equivalent Ge(1) atoms. Both Mo(2)-Ge(2) bond lengths are 2.55 Å. There is one shorter (2.79 Å) and two longer (2.83 Å) Mo(2)-Ge(1) bond lengths. In the third Mo site, Mo(3) is bonded in a 5-coordinate geometry to one Ge(1) and four equivalent Ge(2) atoms. The Mo(3)-Ge(1) bond length is 2.55 Å. There are a spread of Mo(3)-Ge(2) bond distances ranging from 2.56-2.83 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Mo(3), three equivalent Mo(2), and four equivalent Mo(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to one Mo(2), four equivalent Mo(1), and four equivalent Mo(3) atoms.
