The crystal structure described by Lu5Ga3 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 Ga(1) atoms. In the second Lu site, Lu(2) is bonded in a 5-coordinate geometry to five equivalent Ga(1) atoms. Ga(1) 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]
