WCr2Pb crystallizes in the triclinic P1 space group. W(1) is bonded in a 2-coordinate geometry to two equivalent Cr(1) and one Pb(1) atom. There is one shorter (1.39 Å) and one longer (2.05 Å) W(1)-Cr(1) bond length. The W(1)-Pb(1) bond length is 2.08 Å. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a distorted bent 120 degrees geometry to two equivalent W(1) and one Cr(2) atom. The Cr(1)-Cr(2) bond length is 2.58 Å. In the second Cr site, Cr(2) is bonded in a 9-coordinate geometry to one Cr(1), six equivalent Cr(2), and two equivalent Pb(1) atoms. There are four shorter (2.93 Å) and two longer (3.26 Å) Cr(2)-Cr(2) bond lengths. There is one shorter (3.14 Å) and one longer (3.49 Å) Cr(2)-Pb(1) bond length. Pb(1) is bonded in a 2-coordinate geometry to one W(1) and two equivalent Cr(2) atoms.
