Rhenium(I) tricarbonyl complexes with multidentate nitrogen-donor derivatives
摘要:
The reaction of [Re(CO)(5)X] (X = Cl, Br) with a series of six potentially multidentate nitrogen donor ligands (L1-L6) was studied. The ligands L1-L5 are coordinated bidentately in the neutral complexes of the type fac-[Re(CO)(3)X(L)] (1-5). The complex salt [Re(CO)(3)(L6)]Br (6) was formed by the reaction of [Re(CO)(5)Br] with 2-aminobenzaldehyde (aba), in which the tridentate ligand L6 was formed by the Schiff base condensation of three aba molecules. The crystal structures for complexes 1-6 were determined by X-ray single crystal diffraction. UV-Vis absorption spectra of the complexes show the intraligand and MLCT transitions. Electrochemical behaviour of the complexes was studied with cyclic voltammetry. (c) 2012 Elsevier Ltd. All rights reserved.
