| 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. |
