Zirconium (IV) complexes with some polymethylenediimines

J Na’aliya


The syntheses of zirconium (IV) complexes have been carried out by the reaction of oxozirconium (IV) chloride with the appropriate diimines (Schiff bases). The complexes were isolated as yellow solids which are stable to heat. The complexes were found to be insoluble in most solvents. The infrared spectra, elemental analysis and other properties suggest that the complexes are six coordinate. The schiff bases were isolated as yellow crystals with sharp melting points on refluxing 2 – hydroxyl -1- benzaldehyde and the appropriate diamines in methanol.

Keywords: Complexes, crystals, decomposition, characterization and condensation.
