Mixed-ligand complexes of iron(II), iron(III), copper(II), and cobalt(II) with pyrazolonic and 2,2'-bipyridine ligands

摘要

New mixed-ligand complexes, [M_2(BAMP)(bipy)_2][MCl_4]_2, M=Co~(+2)(1), Cu~(+2)(2), [M_2(TAMEN)(bipy)_2][MCl_4]_2, M=Fe~(+2)(3), Co~(2+)(4), and [Fe_2(TAMEN)(bipy)_2][FeCl_6]_2 (5), where BAMP and TAMEN stand for the Mannich bases JV,/V-bis(antipyryl-4-methylene)-piperazine and N,N'-tetra(antipyryl-4-methylene)-l,2-ethane-diamine, respectively, have been obtained and characterized by elemental analyses, conductometric and magnetic susceptibility measurements at room temperature, mass spectrometry, UV-Vis, infrared, and mass spectroscopy, and ~1H NMR spectra for the ligands.
