Ag Rh Cl Cl
RhAgCl2 crystallizes in the monoclinic Cm space group. Rh(1) is bonded in a 5-coordinate geometry to one Ag(1) and four equivalent Cl(1) atoms. The Rh(1)-Ag(1) bond length is 1.89 Å. There are two shorter (2.58 Å) and two longer (2.74 Å) Rh(1)-Cl(1) bond lengths. Ag(1) is bonded in a distorted trigonal non-coplanar geometry to one Rh(1) and two equivalent Cl(1) atoms. Both Ag(1)-Cl(1) bond lengths are 1.46 Å. Cl(1) is bonded in a single-bond geometry to two equivalent Rh(1) and one Ag(1) atom.
