Abstract	Rhenium tricarbonyl diimine complexes have been the subject of much attention, mainly because of their photophysical and photochemical properties and their use in CO2 activation and in supramolecular chemistry and catalyst [1]. Such Re(I) complexes are ideally suited for solar energy conversion dyes, since they display intense luminescence in the visible region of the spectrum with long emission lifetimes. The origin of the emission was attributed to the metal-to-ligand charge transfer (MLCT) state. The photochemical and photophysical properties of these complexes can be fine-tuned by changing the chromophoric, bidentate ligand and/or the ancillary ’’spectator’’ ligands [2]. The structures of the newly prepared N,Nu -bis(diimine)-tricarbonyl rhenium(I) complexes, [Re(CO)3(L)(X)] (X= Cl, CF3COO and L= chelating diimine), determined by X-ray diffraction show that the complexes are the facial isomers and are of istorted octahedral geometries. To the best of our knowledge, there are only few reports concerning the structural analysis of these complexes in which the R is carboxylate group.
