Abstract

A series of new rhenium(I) complexes of the type [Re(CO)3(3,3?-trimethylene-2,2?-biquinoline)(L)](CF 3SO3)n, (L = CF3SO3 -, pyridine (py) or para-substituted pyridine like HO-py, ph-py or NC-py; n = 0 or 1) were prepared and characterized by FTIR, 1H NMR, and UV-vis spectroscopies and by cyclic voltammetry. The pseudo-octahedral facial configuration of these compounds was established by FTIR. The differences found in the spectroscopical and electrochemical results were associated to the effect of the para-position substituent of the L pyridine ligand. © 1998 Elsevier Science Ltd.
