TbScSb is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Tb(1) is bonded in a 5-coordinate geometry to five equivalent Sb(1) atoms. Sc(1) is bonded to four equivalent Sb(1) atoms to form a mixture of distorted corner and edge-sharing ScSb4 cuboctahedra. Sb(1) is bonded in a 9-coordinate geometry to five equivalent Tb(1) and four equivalent Sc(1) atoms.
TbScSb is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Tb(1) is bonded in a 5-coordinate geometry to five equivalent Sb(1) atoms. There are four shorter (3.15 Å) and one longer (3.17 Å) Tb(1)-Sb(1) bond length. Sc(1) is bonded to four equivalent Sb(1) atoms to form a mixture of distorted corner and edge-sharing ScSb4 cuboctahedra. All Sc(1)-Sb(1) bond lengths are 3.07 Å. Sb(1) is bonded in a 9-coordinate geometry to five equivalent Tb(1) and four equivalent Sc(1) atoms.
