N2  - The reactions of chromium hexacarbonyl with triphenylphosphine, tri(m- tolyl)- phosphine (pmt), and tri(p-tolyl)phosphine (ppt) at high temperature yield two series of complexes Cr(CO)3L and [Cr(CO)2L]2, although only the latter could be isolated in a pure state. These dimeric derivatives were characterized by analysis, infrared, N.M.R., and mass spectral measurements. All the data are consistent with a molecular arrangement incorporating &#960;-bonding between chromium and one of the arene rings of the ligand which is also &#963;-bonded through phosphorus to the other metal atom, thus forming a novel, highly unsymmetrical bridge system.
