Re Re Re Re Ag Au
Re4AuAg crystallizes in the trigonal R3m space group. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 5-coordinate geometry to one Re(2), two equivalent Re(1), one Au(1), and one Ag(1) atom. The Re(1)-Re(2) bond length is 1.36 Å. Both Re(1)-Re(1) bond lengths are 0.78 Å. The Re(1)-Au(1) bond length is 1.63 Å. The Re(1)-Ag(1) bond length is 2.70 Å. In the second Re site, Re(2) is bonded in a 6-coordinate geometry to three equivalent Re(1) and three equivalent Au(1) atoms. All Re(2)-Au(1) bond lengths are 3.35 Å. Au(1) is bonded in a 4-coordinate geometry to three equivalent Re(1), three equivalent Re(2), and one Ag(1) atom. The Au(1)-Ag(1) bond length is 1.89 Å. Ag(1) is bonded in a single-bond geometry to three equivalent Re(1) and one Au(1) atom.
