LiMo4Sb crystallizes in the trigonal R3m space group. Li(1) is bonded in a distorted single-bond geometry to one Mo(2) and three equivalent Sb(1) atoms. The Li(1)-Mo(2) bond length is 2.57 Å. All Li(1)-Sb(1) bond lengths are 3.10 Å. There are two inequivalent Mo sites. In the first Mo site, Mo(2) is bonded in a 4-coordinate geometry to one Li(1) and three equivalent Mo(1) atoms. All Mo(2)-Mo(1) bond lengths are 0.91 Å. In the second Mo site, Mo(1) is bonded in a 2-coordinate geometry to one Mo(2), two equivalent Mo(1), and one Sb(1) atom. Both Mo(1)-Mo(1) bond lengths are 0.52 Å. The Mo(1)-Sb(1) bond length is 1.43 Å. Sb(1) is bonded in a 6-coordinate geometry to three equivalent Li(1) and three equivalent Mo(1) atoms.
