Be Be Be Be Re Sb
Be4ReSb crystallizes in the trigonal R3m space group. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a 2-coordinate geometry to two equivalent Be(2), one Re(1), and one Sb(1) atom. Both Be(1)-Be(2) bond lengths are 2.35 Å. The Be(1)-Re(1) bond length is 1.52 Å. The Be(1)-Sb(1) bond length is 1.97 Å. In the second Be site, Be(2) is bonded in a 9-coordinate geometry to six equivalent Be(1) and three equivalent Sb(1) atoms. All Be(2)-Sb(1) bond lengths are 2.84 Å. Re(1) is bonded in a distorted trigonal pyramidal geometry to three equivalent Be(1) and one Sb(1) atom. The Re(1)-Sb(1) bond length is 1.95 Å. Sb(1) is bonded in a 4-coordinate geometry to three equivalent Be(1), three equivalent Be(2), and one Re(1) atom.
