Sb Sb P W
WSb2P crystallizes in the monoclinic Cm space group. W(1) is bonded in a distorted bent 120 degrees geometry to one Sb(1) and one Sb(2) atom. The W(1)-Sb(1) bond length is 3.01 Å. The W(1)-Sb(2) bond length is 3.01 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 5-coordinate geometry to one W(1), one Sb(2), and three equivalent P(1) atoms. The Sb(1)-Sb(2) bond length is 1.77 Å. There is one shorter (1.80 Å) and two longer (2.71 Å) Sb(1)-P(1) bond lengths. In the second Sb site, Sb(2) is bonded in a 5-coordinate geometry to one W(1), one Sb(1), and three equivalent P(1) atoms. There is one shorter (1.71 Å) and two longer (2.65 Å) Sb(2)-P(1) bond lengths. P(1) is bonded in a 2-coordinate geometry to three equivalent Sb(1) and three equivalent Sb(2) atoms.
