Re Re Re Re Sn Bi
Re4SnBi crystallizes in the trigonal R3m space group. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 2-coordinate geometry to one Re(2), two equivalent Re(1), and one Bi(1) atom. The Re(1)-Re(2) bond length is 0.87 Å. Both Re(1)-Re(1) bond lengths are 0.50 Å. The Re(1)-Bi(1) bond length is 1.06 Å. In the second Re site, Re(2) is bonded in a 6-coordinate geometry to three equivalent Re(1) and three equivalent Sn(1) atoms. All Re(2)-Sn(1) bond lengths are 3.39 Å. Sn(1) is bonded in a single-bond geometry to three equivalent Re(2) and one Bi(1) atom. The Sn(1)-Bi(1) bond length is 1.22 Å. Bi(1) is bonded in a 4-coordinate geometry to three equivalent Re(1) and one Sn(1) atom.
