Synthesis and characterization of Pd [II] and Ru [III] complexes with arylidene derivatives of picolinic, nicotinic and isonicotinic acids hydrazides

The complexes of Pd [II] and Ru [III] with arylidene derivatives of picolinic, nicotinic and isonicotinic hydrazides were prepared and characterized by elemental analysis, TGA, DTA, IR, electronic, ESR spectra as well as magnetic measurements. In the light of the results it was concluded that the palladium complexes are of square planar configuration, while the ruthenium complexes exhibit low spin octahedral geometry
