mer-Hydridobis(ethylene)tris(dimethylphenylphosphine)rhenium(I) (1) and cis-hydrido(dinitrogen)-tetrakis(dimethylphenylphosphine)rhenium(I) (2) have been prepared by the reaction of mer-trichloro-tris(dimethylphenylphosphine)rhenium(I) with ethyllithium and n-propyllithium, respectively. X-ray structure analysis reveals that which complexes are octahedral, and in the former complex the two coordinated ethylenes occupy sites perpendicular to each other in cis positions and in the latter complex hydrido and dinitrogen ligands in cis positions. The coordinated ethylene and dinitrogen can be smoothly displaed by dihydrogen to give known trihydrido- or pentahydridorhenium complexes.
