Serendipitous Formation of First Neutral Mononuclear Rh(II) Complex of 1,10-Phenanthroline

摘要

The reaction of RhCl3 with 1,10-phenanthroline followed by a carboxyl funclionalizcd tertiaiyphosphine in refluxing ethanol led to serendipitous formation of a first neutral mononuclear Rh(II) complex of 1,10-phenanthroline as [Rh(H)Cl2(1,10-phen)2] without incorporating the phosphine. This incident was evidenced by elemental analysis, single crystal X-ray diffraction, EPR and Mass spectroscopic studies.
