Andrews, Michael published the artcileA luminescent rhenium(I) complex of 2,7-dimethyl-1,8-naphthyridine: Synthesis, spectroscopy and X-ray crystal structure, Category: naphthyridine, the publication is Transition Metal Chemistry (Dordrecht, Netherlands) (2009), 34(5), 493-497, database is CAplus.
2,7-Dimethyl-1,8-naphthyridine (L1) reacts with pentacarbonylchlororhenium in toluene or chloroform to give the target complex fac-{ReCl(CO)3(L1)}. X-ray crystallog. data were obtained for fac-{ReCl(CO)3(L1)}. The structural and 1H NMR data suggest that the ligand coordinates to the rhenium in a bidentate fashion in both solid and solution states. The complex also is luminescent in both solution and solid states. The fluxionality of the ligand in solution causes ligand-centered emission to be observed in solution, whereas only 3MLCT emission was observed in the solid state. Although the complex was air-stable, the lability of L1 was studied in 1H NMR experiments where CD3OD induced complete ligand dissociation over 24 h, and also in reaction of fac-{ReCl(CO)3(L1)} with one equivalent of 2,2′-bipyridine in chloroform which resulted in quant. ligand exchange.
