Synthesis And Spectral Studies Of Some New Binuclear Thiocyanate Complexes Containing Schiff Base Ligands Derived From 3,4-Diaminotoluene

Abstract

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.
