摘要
Manganese(II)-naphthylazoimidazole complexes using N-3(-) and NCS- as counter ions are characterized as Mn(beta-NaiR)(2)(X)(2)(beta-NaiEt=1-alkyl-2-(naphthyl-beta-azo)imidazole; X = N-3(-), NCS-). The ligands are unsymmetric N(imidazole), N(azo) chelating agents. The microanalytical, spectral (FT-IR, UV-vis), magnetic (bulk moment and EPR) and electrochemical data establish the structure and composition of the complexes. The single crystal X-ray diffraction studies of Mn(beta-NaiEt)(2)(N-3)(2) and Mn(beta-NaiEt)(2)(NCS)(2)(beta-NaiEt=1-ethyl-2-(naphthyl-beta-azo)imidazole) have confirmed the three dimensional structure of the complexes. Cyclic voltammetry exhibits high potential Mn(III)/Mn(II) couple along with azo reductions. The EPR spectra show usual pattern. (C) 2006 Elsevier B.V. All rights reserved.
