The material described by Tb3(Ni3Ga)2 crystallizes in the cubic Im-3m space group. Tb(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 Tb(1), six equivalent Ni(1), and two equivalent Ga(1) atoms. Ga(1) is bonded to six equivalent Tb(1) and six equivalent Ni(1) atoms to form a mixture of face and corner-sharing GaTb6Ni6 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
