TbCl3 crystallizes in the tetragonal P4_2/mnm space group. Tb(1) is bonded to two equivalent Cl(2) and four equivalent Cl(1) atoms to form a mixture of corner and edge-sharing TbCl6 octahedra. The corner-sharing octahedral tilt angles are 46°. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Tb(1) atoms. In the second Cl site, Cl(2) is bonded in a water-like geometry to two equivalent Tb(1) atoms.
TbCl3 crystallizes in the tetragonal P4_2/mnm space group. Tb(1) is bonded to two equivalent Cl(2) and four equivalent Cl(1) atoms to form a mixture of corner and edge-sharing TbCl6 octahedra. The corner-sharing octahedral tilt angles are 46°. Both Tb(1)-Cl(2) bond lengths are 2.66 Å. There are two shorter (2.65 Å) and two longer (2.66 Å) Tb(1)-Cl(1) bond lengths. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Tb(1) atoms. In the second Cl site, Cl(2) is bonded in a water-like geometry to two equivalent Tb(1) atoms.
