A series of cationic cis-dicarbonylrhodium(I) complexes [Rh(L)(CO) 2 ]SbF 6 has been prepared containing 2,2Ј-bipyridine ligands with proximate H-bonding substituents R in the 6-and 6Ј-position (R = OH, NH 2 , COOEt and PO(OEt) 2 ). The solid-state structures have been determined by X-ray crystallography for the complexes where R = OH, NH 2 and COOEt. The molecular structures have revealed metal-metal and π-π interactions between the square-planar complexes resulting in the formation of molecular chains in the solid state.
