ReRhCl2 crystallizes in the triclinic P1 space group. Re(1) is bonded in a 3-coordinate geometry to one Cl(2) and two equivalent Cl(1) atoms. The Re(1)-Cl(2) bond length is 2.95 Å. There is one shorter (1.46 Å) and one longer (2.23 Å) Re(1)-Cl(1) bond length. Rh(1) is bonded in a 3-coordinate geometry to one Cl(1) and two equivalent Cl(2) atoms. The Rh(1)-Cl(1) bond length is 2.17 Å. There is one shorter (2.30 Å) and one longer (2.52 Å) Rh(1)-Cl(2) bond length. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted trigonal planar geometry to two equivalent Re(1) and one Rh(1) atom. In the second Cl site, Cl(2) is bonded in a 3-coordinate geometry to one Re(1) and two equivalent Rh(1) atoms.
