The material structure described by Pr3Co3Ga crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 9-coordinate geometry to two equivalent Co(2), four equivalent Co(1), and three equivalent Ga(1) atoms. In the second Pr site, Pr(2) is bonded in a 9-coordinate geometry to three equivalent Co(2), four equivalent Co(1), and two equivalent Ga(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to two equivalent Pr(2), four equivalent Pr(1), one Co(2), and two equivalent Ga(1) atoms. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to three equivalent Pr(2), four equivalent Pr(1), and two equivalent Co(1) atoms. Ga(1) is bonded to two equivalent Pr(2), six equivalent Pr(1), and four equivalent Co(1) atoms to form a mixture of distorted edge, face, and corner-sharing GaPr8Co4 cuboctahedra. is represented by the CIF file [CIF]
