The material structure described by Al8Mo3 crystallizes in the monoclinic C2/m space group. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to two equivalent Al(3), four equivalent Al(2), and six equivalent Al(1) atoms to form a mixture of distorted face and edge-sharing MoAl12 cuboctahedra. In the second Mo site, Mo(2) is bonded in a 11-coordinate geometry to one Al(1), two equivalent Al(2), three equivalent Al(3), and five equivalent Al(4) atoms. There are four inequivalent Al sites. In the first Al site, Al(1) is bonded in a 12-coordinate geometry to one Mo(2), three equivalent Mo(1), two equivalent Al(1), two equivalent Al(3), and four equivalent Al(2) atoms. In the second Al site, Al(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Mo(1), two equivalent Mo(2), one Al(4), three equivalent Al(3), and four equivalent Al(1) atoms. In the third Al site, Al(3) is bonded in a 12-coordinate geometry to one Mo(1), three equivalent Mo(2), two equivalent Al(1), three equivalent Al(2), and three equivalent Al(4) atoms. In the fourth Al site, Al(4) is bonded in a 12-coordinate geometry to five equivalent Mo(2), one Al(2), three equivalent Al(3), and three equivalent Al(4) atoms. is represented by the CIF file [CIF]
