The structure described by Pr5Ga3 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 6-coordinate geometry to two equivalent Ga(2) and four equivalent Ga(1) atoms. In the second Pr site, Pr(2) is bonded in a 6-coordinate geometry to two equivalent Pr(2) and four equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted q6 geometry to two equivalent Pr(2) and eight equivalent Pr(1) atoms. In the second Ga site, Ga(2) is bonded in a 10-coordinate geometry to eight equivalent Pr(1) and two equivalent Ga(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
