Abstract
New metal complexes of novel Schiff bases derived from the reaction of zirconium (IV) and thorium (IV) ions with N,N′-disalicylidene-l,2-phenylenediamine (H
2
dsp), N,N′-disalicylidene-3,4-diaminotoluene (H
2
dst), 4-nitro-N,N-disalicylidene-1,2-phenylenediamine (H
2
ndsp) were prepared and characterized based on elemental analyses, IR and
1
H NMR spectroscopy, molar conductance, and thermal analyses. The complexes are formed in 1:1 [Metal]:[Ligand] ratio. The molar conductance measurements proved that all these complexes are non-electrolytes. The IR spectra of the ligands and their complexes are used to identify the type of bonding. The thermogravimetric analysis of the complexes shows metal oxide remaining as the final product.
