Abstract: Co (II) and Zn (II) of Ruhemann`s Purple derived from ninhydrin and each of L- Aspartic acid and L-Threonine were successfully synthesized. The two complexes were distinctly colored and stable to atmospheric conditions. The complexes were characterized by elemental analysis, molar conductance and magnetic susceptibility; as well as infrared and electronic spectral studies. The Ruhemann`s Purple was shown to behave as a monobasic tridentate ONO donor. An octahedral geometry is proposed for the two complexes.
