Al Re Re Pb
Re2AlPb crystallizes in the monoclinic Cm space group. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a single-bond geometry to one Al(1) and one Pb(1) atom. The Re(1)-Al(1) bond length is 1.19 Å. The Re(1)-Pb(1) bond length is 3.26 Å. In the second Re site, Re(2) is bonded in a single-bond geometry to one Al(1) and one Pb(1) atom. The Re(2)-Al(1) bond length is 1.27 Å. The Re(2)-Pb(1) bond length is 3.57 Å. Al(1) is bonded in a linear geometry to one Re(1) and one Re(2) atom. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded to one Re(1); one Re(2); and six Pb(1,1) atoms to form a mixture of distorted corner and edge-sharing PbRe2Pb6 hexagonal bipyramids. All Pb(1)-Pb(1,1) bond lengths are 3.00 Å. In the second Pb site, Pb(1) is bonded to one Re(1); one Re(2); and six Pb(1,1) atoms to form a mixture of distorted corner and edge-sharing PbRe2Pb6 hexagonal bipyramids. The Pb(1)-Re(1) bond length is 3.26 Å. The Pb(1)-Re(2) bond length is 3.57 Å. Both Pb(1)-Pb(1) bond lengths are 3.00 Å.
