A 2,6-diacetylpyridine based novel acyclic tridentate compartmental ligand (E)-N-(1-(6-((E)-1-(thiazol-5-ylimino)ethyl)pyridin-2-
yl)ethylidene)thiazol-2-amine was prepared by condensation of 2,6-diacetylpyridine and two equivalent of 2-thiazolamine in ethanol. The
reaction of metal chlorides (Mn(II), Co(II), Ni(II), Cu(II), Zn(II)) and VOSO4.5H2O with the new ligand in methanol results the formation
of deep colored metal complexes with the formula [MLCl]Cl (M=Mn, Ni, and Zn), [MLCl2(H2O)], M=Co, Cu(II), and [VOL(SO4)],
respectively. The free ligand and its metal complexes were characterized by elemental analyses, conductivity measurements, magnetic
susceptibility data, IR, UV-Vis and NMR spectral data. The physical measurements and FTIR spectral data showed that most of the
complexes contain tetrahedrally coordinated central ion(II) except the square-pyramidal vanadyl complex and octahedral geometry for
Co(II) and Cu(II) complexes.
