Abstract
A new ligand, 2(ptolyl)1,2,3,4tetrahydroquinazoline2 carbaldehyde oxime, was synthesized from a condensation reaction of oxoptolylacetaldehyde oxime with 2aminobenzyl- amine and then amineimineoxime complexes of this compound that formed with Co(III) and Ni(II) ions were obtained. All structures were characterized by spectral methods, elemental analysis, magnetic susceptibility, molar conductivity, and thermal analyses. The results that were obtained show that the cyclic ligand, HL, undergoes a ringopening reaction upon complexation with metal ions. The Co(III) and Ni(II) complexes have a metalligand ratio of 1:2 and the imine ligand coordinates through the amine, imine, and oxime groups nitrogen atoms with metal ions.
