Synthesis and characterization of palladium complexes of 3-nitroformazans
摘要:
3-Nitroformazans react with bis(1,1,1,5,5,5-hexafluroacetylacetonato) palladium to afford monometallic complexes. The complexes were characterized via X-ray crystallography, cyclic voltammetry, and electronic spectroscopy. The nature of the aryl substituents on the formazan ligands had a profound effect on the structure and spectroscopy of the complexes, with o-substituted aromatic rings twisted with respect to the ligand, while the p-tolyl substituted derivative adopted a planar structure. The complexes undergo irreversible reductions near -1 V versus Fc/Fc(+). (c) 2008 Elsevier B. V. All rights reserved.
