Lu2Au2In crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent In(1) atoms. In the second Lu site, Lu(2) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent In(1) atoms. Au(1) is bonded in a 8-coordinate geometry to three equivalent Lu(1), three equivalent Lu(2), and two equivalent In(1) atoms. In(1) is bonded in a 12-coordinate geometry to four equivalent Lu(1), four equivalent Lu(2), and four equivalent Au(1) atoms.
Lu2Au2In crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent In(1) atoms. There are two shorter (2.89 Å) and four longer (3.02 Å) Lu(1)-Au(1) bond lengths. All Lu(1)-In(1) bond lengths are 3.49 Å. In the second Lu site, Lu(2) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent In(1) atoms. There are two shorter (2.89 Å) and four longer (2.99 Å) Lu(2)-Au(1) bond lengths. All Lu(2)-In(1) bond lengths are 3.41 Å. Au(1) is bonded in a 8-coordinate geometry to three equivalent Lu(1), three equivalent Lu(2), and two equivalent In(1) atoms. Both Au(1)-In(1) bond lengths are 3.12 Å. In(1) is bonded in a 12-coordinate geometry to four equivalent Lu(1), four equivalent Lu(2), and four equivalent Au(1) atoms.
