Cobalt (II), nickel (II), copper (II) and zinc (II) complexes of 1-(phenyl(phenylamino) methyl)pyrrolidine-2,5-dione and 2-((phenylamino)methyl) isoindoline-1,3-dione and their biological activity

<div align="justify">The new Mannich bases 1-(phenyl(phenylamino)methyl)pyrrolidine-2,5-dione (SBA) was synthesized from the condensation of succinimide, benzaldehyde and aniline. 2-((phenylamino)methyl)isoindoline-1,3-dione (PFA) was derived from pthalimide, formaldehyde and aniline. The general formula of the Co (II), Ni (II), Cu (II) and Zn (II) chloro complexes, ML2X2 are reported. The ligands and the complexes have been characterized by various physical-chemical techniques such as elemental analysis, molar conductance, magnetic susceptibility measurements, infrared and electronic spectra. The spectral analysis to ascertain mode of bonding and overall geometry of the complexes revealed octahedral geometries. </div
