Re Re Pb Cl
Re2PbCl crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Re2PbCl clusters. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a distorted linear geometry to one Re(2) and one Cl(1) atom. The Re(1)-Re(2) bond length is 1.25 Å. The Re(1)-Cl(1) bond length is 3.05 Å. In the second Re site, Re(2) is bonded in a single-bond geometry to one Re(1) atom. Pb(1) is bonded in a single-bond geometry to one Cl(1) atom. The Pb(1)-Cl(1) bond length is 0.77 Å. Cl(1) is bonded in a single-bond geometry to one Re(1) and one Pb(1) atom.
