Li4TaMo crystallizes in the trigonal R3m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 4-coordinate geometry to one Li(2), two equivalent Li(1), one Ta(1), and one Mo(1) atom. The Li(1)-Li(2) bond length is 2.13 Å. Both Li(1)-Li(1) bond lengths are 1.23 Å. The Li(1)-Ta(1) bond length is 2.53 Å. The Li(1)-Mo(1) bond length is 2.78 Å. In the second Li site, Li(2) is bonded in a 9-coordinate geometry to three equivalent Li(1), three equivalent Ta(1), and three equivalent Mo(1) atoms. All Li(2)-Ta(1) bond lengths are 2.91 Å. All Li(2)-Mo(1) bond lengths are 2.85 Å. Ta(1) is bonded in a 3-coordinate geometry to three equivalent Li(1), three equivalent Li(2), and three equivalent Mo(1) atoms. All Ta(1)-Mo(1) bond lengths are 2.97 Å. Mo(1) is bonded in a 9-coordinate geometry to three equivalent Li(1), three equivalent Li(2), and three equivalent Ta(1) atoms.
