Synthesis and Characterization of Ruthenium (III) Complexes with Substituted Nitrones

Abstract

ABSTRACT New series of complexes of general [Ru(Cl)2(H2O)2.L]nH2O ; where LH=[α-(2-hydroxy-1-naphthyl)-N-(p-R-phenyl nitrone] n=0-6 and R=H, Cl , Br , COCH3 , NHCOCH3 , NH2 and CH3 were formula synthesized and characterized by their elemental analysis(CHN) , molar conductance , magnetic moments , infrared and electronic spectral measurements. The Ligand (L) acted as a bidentate, univalent toward the ruthenium (III( ion via the two oxygen atoms of, the nitrone and naphtholic groups, with the presence of two chloride ions and two aqua molecules the most probable octahedral geometry around each ruthenium ion in each complex. The elemental analysis as well the infrared spectra revealed the presence of lattice water molecules outside the coordination sphere. Their molar conductance measurements revealed the non- electrolytie behavior of the synthesized complexes.
