Analytical Studies of Cu(II), Ni(II) and Pd(II) Complexes with 3-Phenyl-Quinazolin-4(3H)-one-2-Carboxaldehydoxime

Abstract

3-Phenyl quinazolin-4-(3H)-one-2-carboxaldehydoxime forms

water insoluble chelates with Cu(II), Ni(II) and Pd(II). It has been

found to be a selective reagent for the gravimetric estimation of

these metal ions in presence of many interfering ions. All the chelates

have 1 : 2 (metal : ligand) stoichiometry as shown by Job's

method of continuous variation and elemental analysis. Structures

of the metal chelates have been established on the basis of magnetic

measurements, visible and IR spectra.
