Square - Planar complexes of p-[(p-aminophenyl)thio]phenylpyrrole-2-yl-ethylidene with Co(II), Ni(II), Cu(II) and Pd(II) metal ions

Article abstract of DOI:10.1080/00945719608004353

A new bidentate ligand, [p-[(p-aminophenyl)thio] phenyl pyrrole-2yl-ethylidene [HL] (ATPE), was synthesised from bis-(p-aminophenyl)sulphide and 2-acetylpyrrole. Its metal complexes of the general formula ML₂, where M = Co(II), Ni(II), Cu(II) and Pd(II) have been prepared. On the basis of chemical analyses, magnetic moment measurements, electronic and IR spectra, conductance measurements and pH-metric studies, a square-planar geometry of the ligand around the bivalent metallic ions has been suggested. Some thermodynamic functions, such as changes in free energy (ΔF), entropy (ΔS) and enthalpy (ΔH) accompanying the complexation reactions, have been determined. The fungicidal activities of the ligand and its metal complexes have also been studied.
