TaSb2 crystallizes in the monoclinic C2/m space group. Ta(1) is bonded in a 8-coordinate geometry to three equivalent Sb(1) and five equivalent Sb(2) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 6-coordinate geometry to three equivalent Ta(1) and three equivalent Sb(1) atoms. In the second Sb site, Sb(2) is bonded in a 5-coordinate geometry to five equivalent Ta(1) atoms.
TaSb2 crystallizes in the monoclinic C2/m space group. Ta(1) is bonded in a 8-coordinate geometry to three equivalent Sb(1) and five equivalent Sb(2) atoms. There are two shorter (2.86 Å) and one longer (2.91 Å) Ta(1)-Sb(1) bond length. There are a spread of Ta(1)-Sb(2) bond distances ranging from 2.92-2.99 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 6-coordinate geometry to three equivalent Ta(1) and three equivalent Sb(1) atoms. There is one shorter (2.79 Å) and two longer (3.06 Å) Sb(1)-Sb(1) bond lengths. In the second Sb site, Sb(2) is bonded in a 5-coordinate geometry to five equivalent Ta(1) atoms.
