Gd3(Ni3Ga)2 crystallizes in the cubic Im-3m space group. Gd(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 Gd(1), six equivalent Ni(1), and two equivalent Ga(1) atoms. Ga(1) is bonded to six equivalent Gd(1) and six equivalent Ni(1) atoms to form a mixture of face and corner-sharing GaGd6Ni6 cuboctahedra.
Gd3(Ni3Ga)2 crystallizes in the cubic Im-3m space group. Gd(1) is bonded in a 12-coordinate geometry to eight equivalent Ni(1) and four equivalent Ga(1) atoms. There are four shorter (2.77 Å) and four longer (3.06 Å) Gd(1)-Ni(1) bond lengths. All Gd(1)-Ga(1) bond lengths are 3.18 Å. Ni(1) is bonded in a 12-coordinate geometry to four equivalent Gd(1), six equivalent Ni(1), and two equivalent Ga(1) atoms. There are four shorter (2.58 Å) and two longer (2.88 Å) Ni(1)-Ni(1) bond lengths. Both Ni(1)-Ga(1) bond lengths are 2.50 Å. Ga(1) is bonded to six equivalent Gd(1) and six equivalent Ni(1) atoms to form a mixture of face and corner-sharing GaGd6Ni6 cuboctahedra.
