Synthesis Characterizastion of Complexes of Cobalt(II), Nickel(II)and Copper(II)with 2-pyrrolidene-m-nitroaniline and 2-Pyrrolidene-p-nitroaniline Schiff Bases and Their Biological Activity

摘要

Complexes of Co(II),Ni(II)and Cu(II)with the Schiff base ligands PPNA(pyrole-2-carboxaldehyde and p-nitroaniline)and PMNA (pyrrole-2-carboxaldehyde and m-nitroaniline) were synthesised and characterized on the basis of the molar conductance, elemental analysis, IR, magnetic moment and electronic spectra. Complexes were also tested for antifungal activityu. Complexes derived from PPNA are ionic, paramagnetic and octahedral, whereas complexes derived from PMNA are non-ionic, paamagnetic, tetrahedral[Co(II) and Cu(II)] and square-planar[NI(II)]
