Abstract
New complexes cis-[Mo2O5(Hapdhba)(2)], trans-[UO2(Hapdhba)(2)], [Pd(Hapdhba) Cl(H2O)], [Pd(bpy)(Hapdhba)] Cl, [Ag(bpy)(Hapdhba)], [Ru(Hapdhba)(2)(H2O)(2)], [Rh(Hapdhba)(2)Cl(H2O)] and [Au(Hapdhba) Cl-2] are reported, where H2apdhba is the Schiff-base derived from 2-aminopyrimidine and 2,4-dihydroxy benzaldehyde. The complexes were characterized by IR, electronic, H-1 NMR and mass spectra, conductivity, magnetic and thermal measurements. The inhibitive effect of H(2)apdhba for the corrosion of copper in 0.5 M HCl was also determined by potentiodynamic polarization measurements.
