Li3In2 crystallizes in the trigonal R-3m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to three equivalent Li(2) and four equivalent In(1) atoms to form a mixture of distorted edge, face, and corner-sharing LiLi3In4 tetrahedra. In the second Li site, Li(2) is bonded in a distorted linear geometry to six equivalent Li(1) and eight equivalent In(1) atoms. In(1) is bonded in a 5-coordinate geometry to four equivalent Li(1) and four equivalent Li(2) atoms.

In the first Li site, Li(1) is bonded to three equivalent Li(2) and four equivalent In(1) atoms to form a mixture of distorted edge, face, and corner-sharing LiLi3In4 tetrahedra. All Li(1)-Li(2) bond lengths are 2.92 Å. There are three shorter (2.85 Å) and one longer (2.88 Å) Li(1)-In(1) bond length. In the second Li site, Li(2) is bonded in a distorted linear geometry to six equivalent Li(1) and eight equivalent In(1) atoms. There are two shorter (3.02 Å) and six longer (3.30 Å) Li(2)-In(1) bond lengths. In(1) is bonded in a 5-coordinate geometry to four equivalent Li(1) and four equivalent Li(2) atoms.
