Abstract
Two rhenium(I) complexes, [Re(CO)3Br(L n )] (n = 1, 2), (L1= N,N′-bis[1-(4-chlorophenyl)ethylidene]ethane-1,2-diamine and L2 = N,N′-bis[1-(4-nitrophenyl)ethylidene]ethane-1,2-diamine) have been synthesized and characterized by CHN analyses, 1H NMR, IR, and UV-Vis spectroscopy. The molecular structure of [Re(CO)3Br(L1)] is a distorted octahedron around rhenium with one Br, facial arrangement of three CO's, and one diimine. The UV-Vis spectra of the complexes have metal-to-ligand charge transfer bands increasing in wavelength when the L2 ligand is replaced by L1, in agreement with the oxidation potential of the complexes.
