Dimeric and monomeric fac-rhenium(I)tricarbonyl complexes containing 2-(imidazo[1,2-a]pyridin-2-yl)phenolate

Neutral acyclic complexes, dimer (1) and mononuclear complexes (2 and 3), were synthesized from Re2(CO)10, and imidazo[1,2-a]pyridine without/with pyridine (py) or 4-dimethylaminopyridine (DMAP).
