Description :
Pd(II) Complexes with N2O2typetetradentate Schiff bases derived fromo-phenylenediamine and various salicylaldehydes were synthesized and characterised by elemental analysis, magnetic susceptibility, molar conductivity as well as IR, 1H-NMR and electronic spectroscopy.Elemental analysis data proved 1 : 1 stoichiometry. The molar conductance data revealedthe non electrolyticbehaviourofthe complexes. The analytical and spectral data confirm that the Schiff basesact as dibasic tetradentate ligands and coordinated to metal via the two azomethinenitrogens and the two phenolic oxygens. Magnetic susceptibility and electronic spectral data confirm the diamagnetic nature and square planar geometry for the complexes. The powder X- ray diffraction data suggested monoclinic crystal system for these complexes.
Keywords: Pd(II) complexes, Schiff bases, o-phenylenediamine, X- ray diffraction studies.
