W2RePb crystallizes in the monoclinic Cm space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a distorted q6 geometry to one W(2), four equivalent W(1), and four equivalent Pb(1) atoms. The W(1)-W(2) bond length is 3.31 Å. All W(1)-W(1) bond lengths are 3.02 Å. There are a spread of W(1)-Pb(1) bond distances ranging from 3.12-3.18 Å. In the second W site, W(2) is bonded in a 9-coordinate geometry to one W(1), four equivalent W(2), and four equivalent Re(1) atoms. All W(2)-W(2) bond lengths are 3.02 Å. There are a spread of W(2)-Re(1) bond distances ranging from 2.93-3.00 Å. Re(1) is bonded in a single-bond geometry to four equivalent W(2) and one Pb(1) atom. The Re(1)-Pb(1) bond length is 0.26 Å. Pb(1) is bonded in a single-bond geometry to four equivalent W(1) and one Re(1) atom.
