[1,1′-bis(diphenylphosphino)ferrocene-κ2P,P′](1,5-cyclooctadiene)rhodium(I) trifluoromethanesulfonate dichloromethane disolvate

The title compound, [Rh(C8H12)(C34H28P2Fe)]CF3SO3.2CH(2)Cl(2) or [RhFe(C8H12)(C17H14P)(2)]CF3SO3.2CH(2)Cl(2), was synthesized by reacting 1,1'-bis(diphenylphosphino)ferrocene (dppf) with [Rh(1,5-cyclooctadiene)(THF)(2)](+) in tetrahydrofuran (THF), and shows dppf acting as a P,P'-bidentate chelating ligand. The compound crystallizes in the space group P2(1)/n and features one crystallographically unique Rh+ metal centre, which appears in a distorted square-planar geometry.
