Synthesis, characterization and biocidal studies of Ni(II), Cu(II), Co(II), Fe(II), Mn(II) and Zn(II) complexes Containing tetra dentate and neutral bi dentate schiff base

摘要

Tetra dentate schiff base N,N’-bis[2-hydroxyacetophenone]ethylenediamine (OAcPh-en) were formed by the 2:1 molar condensation of 2-hydroxyacetophenone with ethylenediamine. Their Ni(II), Cu(II), Co(II), Mn(II), Fe(II) and Zn(II) diaquo complexes (I) were synthesized. The neutral bidentate derived from benzaldehyde and ethylenediamine or o-phenylinediamine in 1:1 molar ratio in alcoholic solution yield bis[benzylidene]ethylenediamine (Ben-en) or bis[benzylidene]o-phenylinediamine (Ben-opd) (II). Further reaction between (I) and (II) in alcohol yielded mixed ligand complexes. The characterization of these newly synthesized mixedligand complexes were done by elemental analysis, magnetic measurements, Infrared spectra and uv-visible spectra, thermo gravimetric analysis, biocidal studies have also been under taken.
