The divalent metal ions Mn, Cu and Zn complexes with Schiff base
derived from a reaction of salicylaldehyde with L- valine amino acid (L)
have been prepared and investigated by using different physicochemical
techniques in terms; elemental analysis, molar conductance
measurements, infrared, electronic and electron paramagnetic resonance
spectroscopies. The elemental analysis exhibited the formation of 1:1 [M:
L] ratio. The molar conductance measurements of the complexes
indicated the presence of a non-electrolytic nature. The infrared spectral
data displayed coordination sites of the free Schiff base toward the metal
ions under investigation. The electronic spectral results of Schiff base and
its complexes revealed the existence of π-π
* (phenyl), n-π* (H-C =N)
transitions, and these results suggest that all the complexes are octahedral.
The electron paramagnetic resonance spectral data were reported. The
free Schiff base, metal ions and their complexes affected on germination
of root and shoot lengths of gazone (cynadon) and cucumber seeds
