TbNiIn crystallizes in the hexagonal P-62m space group. Tb(1) is bonded in a 11-coordinate geometry to one Ni(1), four equivalent Ni(2), and six equivalent In(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent Tb(1) and six equivalent In(1) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to six equivalent Tb(1) and three equivalent In(1) atoms. In(1) is bonded in a 10-coordinate geometry to six equivalent Tb(1), two equivalent Ni(1), and two equivalent Ni(2) atoms.
TbNiIn crystallizes in the hexagonal P-62m space group. Tb(1) is bonded in a 11-coordinate geometry to one Ni(1), four equivalent Ni(2), and six equivalent In(1) atoms. The Tb(1)-Ni(1) bond length is 3.06 Å. All Tb(1)-Ni(2) bond lengths are 2.93 Å. There are two shorter (3.12 Å) and four longer (3.27 Å) Tb(1)-In(1) bond lengths. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent Tb(1) and six equivalent In(1) atoms. All Ni(1)-In(1) bond lengths are 2.66 Å. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to six equivalent Tb(1) and three equivalent In(1) atoms. All Ni(2)-In(1) bond lengths are 2.82 Å.
