Reaction of cis-n4> or <2> with one or two molar equivalents of (o-diphenylphosphinophenyl)amine (H2L) respectively gives the mononuclear halogenocarbonylrhodium(I) complexes .These new compounds were found to react with air to give the novel amido-bridged rhodium(II) metal-metal bonded dimers <2> .The chloro species (2a) was also shown to react with base in inert atmosphere to generate the rhodium(I) amido-bridged dimer <2> (4), which reacts with one molar equivalent of halogen to produce (5) or with excess halogen to give the monomeric rhodium(III) mer-trihalogeno complexes .The chloro rhodium(II) dimer (5a) has been characterised by X-ray structure analysis.Crystals of (5a)*EtOH are monoclinic, space group P2₁/c, with a=14.669(3), b=14.754(3), c=18.233(4) Angstroem, β=92.46(4) degree, and Z=4.Full-matrix refinement of 3498 unique data with I>/=3?(I) (3<θ<25 degree) gave R=0.045 and R'=0.042.
