Abstract
|
|
|
|
New complexes cis-[Mo₂O₃(Hapdhba)₂], trans-[UO₂(Hapdhba)₂], [Pd(Hapdhba)Cl(H₂O)], [Pd(bpy)(Hapdhba)]Cl, [Ag(bpy)(Hapdhba)], [Ru(Hapdhba)₂(H₂O₂], [Rh(Hapdhba)₂Cl(H₂O)] and [Au(Hapdhba)Cl₂] are reported, where H₂apdhba is the Schiff-base derived from 2-aminopyrimidine and 2,4-dihydroxy benzaldehyde. The complexes were characterized by IR, electronic, ¹H NMR and mass spectra, conductivity, magnetic and thermal measurements. The inhibitive effect of H₂apdhba for the corrosion of copper in 0.5 M HCl was also determined by potentiodynamic polarization measurements.
