The material described by Lu5In4 crystallizes in the hexagonal P6_3/mcm 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 In(2) atoms. In the second Lu site, Lu(2) is bonded in a 7-coordinate geometry to two equivalent In(1) and five equivalent In(2) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded to six equivalent Lu(2) atoms to form distorted face-sharing InLu6 octahedra. In the second In site, In(2) is bonded in a 9-coordinate geometry to four equivalent Lu(1) and five equivalent Lu(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
