Lu2In crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 14-coordinate geometry to two equivalent Lu(1), six equivalent Lu(2), and six equivalent In(1) atoms. In the second Lu site, Lu(2) is bonded to six equivalent Lu(1) and five equivalent In(1) atoms to form a mixture of distorted corner and face-sharing LuLu6In5 trigonal bipyramids. In(1) is bonded in a 11-coordinate geometry to five equivalent Lu(2) and six equivalent Lu(1) atoms.
Lu2In crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 14-coordinate geometry to two equivalent Lu(1), six equivalent Lu(2), and six equivalent In(1) atoms. Both Lu(1)-Lu(1) bond lengths are 3.28 Å. All Lu(1)-Lu(2) bond lengths are 3.44 Å. All Lu(1)-In(1) bond lengths are 3.44 Å. In the second Lu site, Lu(2) is bonded to six equivalent Lu(1) and five equivalent In(1) atoms to form a mixture of distorted corner and face-sharing LuLu6In5 trigonal bipyramids. There are three shorter (3.03 Å) and two longer (3.28 Å) Lu(2)-In(1) bond lengths. In(1) is bonded in a 11-coordinate geometry to five equivalent Lu(2) and six equivalent Lu(1) atoms.
