Hg Bi Rh Rh
Rh2HgBi crystallizes in the triclinic P1 space group. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 6-coordinate geometry to two equivalent Rh(2), two equivalent Hg(1), and two equivalent Bi(1) atoms. There is one shorter (2.24 Å) and one longer (2.53 Å) Rh(1)-Rh(2) bond length. There is one shorter (2.40 Å) and one longer (3.02 Å) Rh(1)-Hg(1) bond length. There is one shorter (2.57 Å) and one longer (3.16 Å) Rh(1)-Bi(1) bond length. In the second Rh site, Rh(2) is bonded in a 6-coordinate geometry to two equivalent Rh(1), two equivalent Hg(1), and two equivalent Bi(1) atoms. There is one shorter (2.57 Å) and one longer (3.16 Å) Rh(2)-Hg(1) bond length. There is one shorter (2.40 Å) and one longer (3.02 Å) Rh(2)-Bi(1) bond length. Hg(1) is bonded in a 1-coordinate geometry to two equivalent Rh(1), two equivalent Rh(2), and one Bi(1) atom. The Hg(1)-Bi(1) bond length is 0.95 Å. Bi(1) is bonded in a 1-coordinate geometry to two equivalent Rh(1), two equivalent Rh(2), and one Hg(1) atom.
