Tb3Pd2NiAl3 crystallizes in the hexagonal P-62m space group. Tb(1) is bonded in a 11-coordinate geometry to four equivalent Pd(1), one Ni(1), and six equivalent Al(1) atoms. Pd(1) is bonded in a 9-coordinate geometry to six equivalent Tb(1) and three equivalent Al(1) atoms. Ni(1) is bonded in a distorted q6 geometry to three equivalent Tb(1) and six equivalent Al(1) atoms. Al(1) is bonded to six equivalent Tb(1), two equivalent Pd(1), two equivalent Ni(1), and two equivalent Al(1) atoms to form a mixture of distorted edge, corner, and face-sharing AlTb6Al2Ni2Pd2 cuboctahedra.
Tb3Pd2NiAl3 crystallizes in the hexagonal P-62m space group. Tb(1) is bonded in a 11-coordinate geometry to four equivalent Pd(1), one Ni(1), and six equivalent Al(1) atoms. All Tb(1)-Pd(1) bond lengths are 2.94 Å. The Tb(1)-Ni(1) bond length is 2.87 Å. There are four shorter (3.21 Å) and two longer (3.27 Å) Tb(1)-Al(1) bond lengths. Pd(1) is bonded in a 9-coordinate geometry to six equivalent Tb(1) and three equivalent Al(1) atoms. All Pd(1)-Al(1) bond lengths are 2.80 Å. Ni(1) is bonded in a distorted q6 geometry to three equivalent Tb(1) and six equivalent Al(1) atoms. All Ni(1)-Al(1) bond lengths are 2.57 Å. Al(1) is bonded to six equivalent Tb(1), two equivalent Pd(1), two equivalent Ni(1), and two equivalent Al(1) atoms to form a mixture of distorted edge, corner, and face-sharing AlTb6Al2Ni2Pd2 cuboctahedra. Both Al(1)-Al(1) bond lengths are 2.74 Å.
