| Abstract | ||
| Reactions of the hydrazone ligand; 2-[α-(acetyloxime)ethylidenehydrazino]-4,6-dimethylquinoline (MOHQ) with various cobalt(II) salts (acetate, nitrate, sulfate and chloride) yielded dimer, mono and binuclear complexes. The successfully prepared complexes (1-4) have been characterized by using different techniques including elemental analyses, infra-red, electronic and mass spectra, magnetic susceptibility and molar conductivity measurements. The results illustrated that MOHQ behaves as bidentate (NO) and tridentate (NNO) chelating agent. UV/Vis spectra in binary solvent mixtures of Co complexes have been investigated. Co complexes (1-3) under study are preferring water than solvation. The hyperchem program was used to determine geometrical and structural optimizations of cobalt complexes at a PM3 level. | ||
