La2In crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 14-coordinate geometry to two equivalent La(1), six equivalent La(2), and six equivalent In(1) atoms. In the second La site, La(2) is bonded to six equivalent La(1) and five equivalent In(1) atoms to form a mixture of distorted corner and face-sharing LaLa6In5 trigonal bipyramids. In(1) is bonded in a 11-coordinate geometry to five equivalent La(2) and six equivalent La(1) atoms.
La2In crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 14-coordinate geometry to two equivalent La(1), six equivalent La(2), and six equivalent In(1) atoms. Both La(1)-La(1) bond lengths are 3.58 Å. All La(1)-La(2) bond lengths are 3.72 Å. All La(1)-In(1) bond lengths are 3.72 Å. In the second La site, La(2) is bonded to six equivalent La(1) and five equivalent In(1) atoms to form a mixture of distorted corner and face-sharing LaLa6In5 trigonal bipyramids. There are three shorter (3.26 Å) and two longer (3.58 Å) La(2)-In(1) bond lengths. In(1) is bonded in a 11-coordinate geometry to five equivalent La(2) and six equivalent La(1) atoms.
