[RE(CO)(3)(3,3'-TRIMETHYLENE-2,2'-BIQUINOLINE) (P-SUBSTITUTED-PY)](- PREPARATION AND CHARACTERIZATION() COMPLEXES )

A series of new rhenium(I) complexes of the type [Re(CO)(3)(3,3'-trime thylene-2,2'-biquinoline) (L)](CF3SO3)(n), (L = CF3 SO3- pyridine (py) or para-substituted pyridine like KO-py, ph-py or NC-py; n = 0 or 1) were prepared and characterized by FTIR, H-1 NMR, and UV-vis spectrosc opies and by cyclic voltammetry. The pseudo-octahedral facial configur ation of these compounds was established by FTIR. The differences foun d in the spectroscopical and electrochemical results were associated t o the effect of the para position substituent of the L pyridine ligand . (C) 1998 Elsevier Science Ltd.
