The structure described by Pr3(Ni3Ga)2 crystallizes in the cubic Im-3m space group. Pr(1) is bonded in a 12-coordinate geometry to eight equivalent Ni(1) and four equivalent Ga(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to four equivalent Pr(1), four equivalent Ni(1), and two equivalent Ga(1) atoms. Ga(1) is bonded to six equivalent Pr(1) and six equivalent Ni(1) atoms to form a mixture of corner and face-sharing GaPr6Ni6 cuboctahedra. is represented by the CIF file [CIF]
