Synthesis And Spectral Studies Of Some New Binuclear Thiocyanate Complexes Containing Schiff Base Ligands Derived From 3,4-Diaminotoluene
New Schiff base ligands L1,L2 and L3 were synthesized from the reaction of 3,4- diaminotoluene with indole-3-caboxaldehyde , 4-morpholine carboxaldehyde or 2-naphthaldehyde. Complexes of CoCd(SCN)4 with those ligands have been synthesized and characterized. The characterization of ligands and their complexes was done by elemental analysis, molar conductance, 1H, 13C-NMR, mass spectra, magnetic susceptibility, infrared, and electronic spectral studies. All the synthesized ligands were bidentate, and The complexes are monomeric binuclear mixed metal bridges of type LCo(NCS)2Cd(SCN)2 ( L= L1,L2 or L3), non-electrolytes and have a four-coordinate number corresponding to tetrahedral geometry.
