Tb Zn In In
TbZnIn2 crystallizes in the trigonal R3m space group. Tb(1) is bonded in a distorted linear geometry to three equivalent Zn(1), one In(1), and one In(2) atom. All Tb(1)-Zn(1) bond lengths are 3.01 Å. The Tb(1)-In(1) bond length is 2.37 Å. The Tb(1)-In(2) bond length is 2.37 Å. Zn(1) is bonded in a 7-coordinate geometry to three equivalent Tb(1), one In(1), and three equivalent In(2) atoms. The Zn(1)-In(1) bond length is 2.37 Å. All Zn(1)-In(2) bond lengths are 3.21 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a distorted linear geometry to one Tb(1) and one Zn(1) atom. In the second In site, In(2) is bonded in a single-bond geometry to one Tb(1) and three equivalent Zn(1) atoms.
