BaSb3 crystallizes in the monoclinic C2/m space group. Ba(1) is bonded in a 9-coordinate geometry to one Sb(2) and eight equivalent Sb(1) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 6-coordinate geometry to four equivalent Ba(1), one Sb(1), and one Sb(2) atom. In the second Sb site, Sb(2) is bonded in a 4-coordinate geometry to one Ba(1), one Sb(2), and two equivalent Sb(1) atoms.
