New chloro- and trifluoroacetato tricarbonylrhenium(I) complexes with a N,N′-bis(benzophenone)-1,2-diiminoethane Schiff base ligand: Spectral and structural studies
摘要:
The reaction of Re(CO)(5)Cl with the chelating ligand N,N-bis(benzophenone)-1,2-diiminoethane (bz(2)en) afforded the neutral fac[Re(CO)(3)(bz(2)en)Cl]. The subsequent reaction with AgOCOCF3 gave fac-[Re(CO)(3)(bz(2)en)OCOCF3]. Their pseudooctahedral fac structures have been established by FTIR, UV-Vis, H-1, C-13 NMR and have been confirmed by X-ray diffraction analysis. The electrochemical behaviour of the investigated complexes has been studied by cyclic voltammetry. (c) 2007 Elsevier Ltd. All rights reserved.
