COPPER(II), COBALT(III), NICKEL(II), PALLADIUM(II), AND ZINC(II) COMPLEXES OF THE SCHIFF BASE LIGANDS DERIVED FROM 2,6-DIACETYLPYRIDINE AND PHTHALDIALDEHYDE
摘要:
Two new ligands, N,N ' -bis[2-hydroxy-3-methoxy-N- (pyridyl) benzylamine]-2,6-di acetylidenepyridine (H2L ') and N, N ' -bis [2-hydroxy-3-methoxy-N-(pyridyl)benzylamine]- 1,2-phthaldialdimine (H2L ") and their Cu(II), Co(III), Ni(II), Pd(II) and Zn(II) complexes have been prepared and characterized by elemental analyses, IR, electronic spectra, magnetic moments, H-1 and C-13 NMR spectra, mass spectral and molar conductance data. The mononuclear Co(III) complexes of these ligands have been isolated with two molecules of DMF. While the Co(III) complex of H2L ' is a 1:1 electrolyte, the other complexes and ligands are non-electrolytes. The ligands H2L ' and H2L " and some of their complexes show antimicrobial activity against bacteria and yeast.
