Abstract
Schiff base ligand, (E)-methyl 2-(5-bromo-2-hydroxybenzylideneamino)-6-phenyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate (L) generated from condensation of 5-bromo-salicylaldehyde with methyl 2-amino-6-methyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxylate and its Co(II) and Pd(II) metal complexes were prepared by using a molar ratio of ligand:metal as 1:1. The complex compounds were obtained by the coordination of donor atoms of the ligand according to the spectral data. The structures of the obtained complex compounds were determined by elemental analysis, fourier transform infrared, 1H and 13C nuclear magnetic resonance, ultraviolet–visible, mass spectrometry, thermogravimetry–differential thermal analysis and magnetic susceptibility techniques. The optical features of Schiff base ligand and its metal complex compounds were compared for different solvents and molarities.
