Planare Dicarbonylrhodium(I)- und -iridium(I) -Komplexe mit polarisierbaren aromatischen Liganden / Planar Dicarbonylrhodium(I) and Iridium(I) Complexes with Polarizable Aromatic Ligands

Some new transition metal complexes of the general type M(CO)2(L-L), where M stands for Ir(I), Rh(I) and L-L for a bidentate mononegative ligand are described. They were characterized by means of analytical data and their IR and PMR spectra. The chemical and solid state properties of these compounds are related to the strength of the intermolecular metal-metal interactions.
