The material structure described by Sm3(Ni3Ga)2 crystallizes in the cubic Im-3m space group. Sm(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 12-coordinate geometry to four equivalent Sm(1), six equivalent Ni(1), and two equivalent Ga(1) atoms. Ga(1) is bonded to six equivalent Sm(1) and six equivalent Ni(1) atoms to form a mixture of corner and face-sharing GaSm6Ni6 cuboctahedra. is represented by the CIF card [CIF]
