Synthesis And Structural Studies On Metal Complexes Derived From The Reaction Between Ninhydrin And Each Of Aspartic Acid And Threonine Separately In The Presence Of Co (ii) And Zn (ii).
Co (II) and Zn (II) of Ruhemann`s Purple derived from ninhydrin and each ofrnL- Aspartic acid and L-Threonine were successfully synthesized. The two complexesrnwere distinctly colored and stable to atmospheric conditions. The complexes wererncharacterized by elemental analysis, molar conductance and magnetic susceptibility; asrnwell as infrared and electronic spectral studies. The Ruhemann`s Purple was shown tornbehave as a monobasic tridentate ONO donor. An octahedral geometry is proposed forrnthe two complexes.rnKey words: Co (II) & Zn (II) complexes, ninhydrin, Ruhemann`srnPurple, Aspartic acid, Threonine
