Abstract

New complexes of Rh(I), [RhCl(CO)(μ-L)] 2 and AcacRh(CO)L, have been obtained with L=1,3,2-dioxaphosphorinane containing an exocyclic codeine fragment. The complexes were characterized by 1H-, 13C-, 31P-NMR, IR spectroscopy, plasma desorption mass spectrometry, X-ray photoelectron spectroscopy and sedimentation analysis. It was found that the chlorocarbonyl rhodium complex is a dimer with the bridge-type P,N-bidentate ligands coordinated in the ‘head to tail’ mode. The same ligand in the acetylacetonate complex was found to be P-monodentate.
