Abstract
IN THE PRESENT work, dithranol (Dithr) reacts with Ni(II), Zn(II), Zr(IV), La(III), and Th(IV) in presence of heterocyclic ligand 8-hydroxyquinoline (8HQ) in acetone forming new mixed ligand complexes. The structures of the synthesized complexes were characterized by conventional techniques including melting point, molar conductivity, magnetic properties, elemental analyses, infrared, ultraviolet-visible, 1H nuclear magnetic resonance, and X-ray powder diffraction (XRD) spectra, as well as thermogravimetric (TG) and differential thermogravimetric (DTG) analyses. The molar conductance values of the metal complexes in dimethyl sulphoxide (DMSO) indicated that the complexes were found to be electrolytes with different ratios. The magnetic susceptibility measurements for Ni(II) complex is 3.1 BM with distorted octahedral geometry. TG/DTG studies confirmed the chemical formula for these complexes and established the thermal decomposition processes ended with the formation of metal oxide contaminated with carbon atom. The infrared spectra of the complexes showed shift for ν(O-H) and ν(C=N) in all complexes, which indicated the coordination of oxygen atom of phenolic group and nitrogen atom of pyridine ring of 8HQ with metal ions. X-ray powder diffraction analysis of the compounds showed that Dithr, 8HQ, and their metal complexes display crystalline peaks except Zr(IV) and La(III) complexes.
