B Sb Sb W
WBSb2 crystallizes in the monoclinic Cm space group. W(1) is bonded in a distorted single-bond geometry to one B(1) and one Sb(1) atom. The W(1)-B(1) bond length is 1.68 Å. The W(1)-Sb(1) bond length is 2.86 Å. B(1) is bonded in a 2-coordinate geometry to one W(1) and three equivalent Sb(2) atoms. There is one shorter (1.71 Å) and two longer (2.60 Å) B(1)-Sb(2) bond lengths. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted bent 150 degrees geometry to one W(1) and one Sb(2) atom. The Sb(1)-Sb(2) bond length is 1.71 Å. In the second Sb site, Sb(2) is bonded in a 4-coordinate geometry to three equivalent B(1) and one Sb(1) atom.
