LiMgIn4 crystallizes in the trigonal R3m space group. Li(1) is bonded in a tetrahedral geometry to one Mg(1) and three equivalent In(1) atoms. The Li(1)-Mg(1) bond length is 2.36 Å. All Li(1)-In(1) bond lengths are 3.04 Å. Mg(1) is bonded in a distorted rectangular see-saw-like geometry to one Li(1) and three equivalent In(1) atoms. All Mg(1)-In(1) bond lengths are 2.05 Å. There are two inequivalent In sites. In the first In site, In(2) is bonded in a 3-coordinate geometry to three equivalent In(1) atoms. All In(2)-In(1) bond lengths are 1.67 Å. In the second In site, In(1) is bonded in a 5-coordinate geometry to one Li(1), one Mg(1), one In(2), and two equivalent In(1) atoms. Both In(1)-In(1) bond lengths are 0.96 Å.
