Novel tridentate Schiff base ligand derived from the 2-aminobenzenthiol and 8-hydroxy-7-quinolinecarboxaldehyde (oxine) and its metal complexes have been prepared. The reaction of a solution of 7-(2,3-dihydro-1,3-benzothiazol- 2-yl)quinolin-8-ol (H2L) with di-and tetravalent transition metals have been studied chemically and biologically. The optimized bond lengths, bond angles and calculated the quantum chemical parameters for the ligand (H2L) [the cyclic form (A) and the Schiff base form (B)] were investigated. The complexes have been characterized by elemental analyses, IR spectra, thermal analyses and 1H-NMR spectroscopy. The spectral studies of the isolated complexes showed that the rearrangement of the benzothiazoline to the Schiff base had occurred. The data suggest that the Co(II) and Ni(II) complexes are binuclear and octahedral dimmers, while the rest are monomeric with squa.. View More»
