Bi Rh Rh Br
Rh2BiBr crystallizes in the monoclinic Pm space group. Rh(1) is bonded in a 5-coordinate geometry to one Rh(1), two equivalent Bi(1), and two equivalent Br(1) atoms. The Rh(1)-Rh(1) bond length is 1.82 Å. There is one shorter (2.41 Å) and one longer (3.14 Å) Rh(1)-Bi(1) bond length. There is one shorter (2.41 Å) and one longer (3.14 Å) Rh(1)-Br(1) bond length. Bi(1) is bonded in a distorted single-bond geometry to four equivalent Rh(1) and one Br(1) atom. The Bi(1)-Br(1) bond length is 1.58 Å. Br(1) is bonded in a 3-coordinate geometry to four equivalent Rh(1) and one Bi(1) atom.
