Sb Pb W
WPbSb crystallizes in the monoclinic Cm space group. W(1) is bonded in a single-bond geometry to one Pb(1) and one Sb(1) atom. The W(1)-Pb(1) bond length is 2.99 Å. The W(1)-Sb(1) bond length is 0.41 Å. Pb(1) is bonded to one W(1), four equivalent Pb(1), and one Sb(1) atom to form a mixture of distorted corner and edge-sharing PbSbPb4W octahedra. The corner-sharing octahedra are not tilted. All Pb(1)-Pb(1) bond lengths are 3.35 Å. The Pb(1)-Sb(1) bond length is 3.42 Å. Sb(1) is bonded in a single-bond geometry to one W(1) and one Pb(1) atom.
