Description 565-571
Unsymmetrical Schiff base glyoxal salicylaldehyde succinic acid dihydrazide (gssdh), and their Co(II), Ni(II), Cu(II),
and Zn(II) complexes have been synthesized and analyzed. These complexes' structures are explained based on magnetic,
electronic, IR, and NMR (1H and 13C) spectral studies. These ligands show monobasic tetra-dentate behavior, bonding
through C=O, two C=N, and a phenolate group. Ni(II) complex show square planar geometry while Cu(II) and Co(II)
complexes exhibit tetrahedral geometry in the solid-state shown by electronic spectra. However, Co(II) and Cu(II)
complexes adopt octahedral geometry in DMSO solution. The insecticidal activity of these compounds is tested, and
compared their activity with their standard. Synthesized compounds show moderate insecticidal activity at higher
concentrations. At low concentrations, these compounds have anti-fungal and antibacterial properties but do not show the
pesticide property.
