WCrCdPb crystallizes in the trigonal R3m space group. W(1) is bonded in a 11-coordinate geometry to three equivalent Cr(1), four equivalent Cd(1), and four equivalent Pb(1) atoms. All W(1)-Cr(1) bond lengths are 2.81 Å. There are three shorter (2.77 Å) and one longer (3.64 Å) W(1)-Cd(1) bond length. There are three shorter (2.77 Å) and one longer (3.64 Å) W(1)-Pb(1) bond length. Cr(1) is bonded in a single-bond geometry to three equivalent W(1), three equivalent Cd(1), and one Pb(1) atom. All Cr(1)-Cd(1) bond lengths are 2.77 Å. The Cr(1)-Pb(1) bond length is 0.78 Å. Cd(1) is bonded in a 10-coordinate geometry to four equivalent W(1), three equivalent Cr(1), and three equivalent Pb(1) atoms. All Cd(1)-Pb(1) bond lengths are 2.81 Å. Pb(1) is bonded in a single-bond geometry to four equivalent W(1), one Cr(1), and three equivalent Cd(1) atoms.
