Zn Re Re Pb
Re2ZnPb crystallizes in the monoclinic Cm space group. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded to six equivalent Re(1), one Zn(1), and one Pb(1) atom to form distorted ReZnRe6Pb hexagonal bipyramids that share corners with six equivalent Re(1)ZnRe6Pb hexagonal bipyramids, edges with six equivalent Pb(1)Re2Pb6 hexagonal bipyramids, and edges with twelve equivalent Re(1)ZnRe6Pb hexagonal bipyramids. All Re(1)-Re(1) bond lengths are 2.96 Å. The Re(1)-Zn(1) bond length is 2.88 Å. The Re(1)-Pb(1) bond length is 3.15 Å. In the second Re site, Re(2) is bonded in a single-bond geometry to one Zn(1) and one Pb(1) atom. The Re(2)-Zn(1) bond length is 0.08 Å. The Re(2)-Pb(1) bond length is 3.15 Å. Zn(1) is bonded in a single-bond geometry to one Re(1) and one Re(2) atom. Pb(1) is bonded to one Re(1), one Re(2), and six equivalent Pb(1) atoms to form distorted PbRe2Pb6 hexagonal bipyramids that share corners with six equivalent Pb(1)Re2Pb6 hexagonal bipyramids, edges with six equivalent Re(1)ZnRe6Pb hexagonal bipyramids, and edges with twelve equivalent Pb(1)Re2Pb6 hexagonal bipyramids. All Pb(1)-Pb(1) bond lengths are 2.96 Å.
