WIrPbSn crystallizes in the trigonal R3m space group. W(1) is bonded in a 11-coordinate geometry to four equivalent Ir(1), four equivalent Pb(1), and three equivalent Sn(1) atoms. There are three shorter (2.80 Å) and one longer (3.56 Å) W(1)-Ir(1) bond length. There are three shorter (2.80 Å) and one longer (3.56 Å) W(1)-Pb(1) bond length. All W(1)-Sn(1) bond lengths are 2.87 Å. Ir(1) is bonded in a single-bond geometry to four equivalent W(1), three equivalent Pb(1), and one Sn(1) atom. All Ir(1)-Pb(1) bond lengths are 2.87 Å. The Ir(1)-Sn(1) bond length is 1.09 Å. Pb(1) is bonded in a 11-coordinate geometry to four equivalent W(1), three equivalent Ir(1), and four equivalent Sn(1) atoms. There are three shorter (2.80 Å) and one longer (3.56 Å) Pb(1)-Sn(1) bond length. Sn(1) is bonded in a single-bond geometry to three equivalent W(1), one Ir(1), and four equivalent Pb(1) atoms.
