A novel hexadentate ligand, N-(pyridin-2-ylmethyl)-N,N'-(bis-(2-(pyridin-2-ylmethylthio))ethyethanamine) (L), containing "N4S2" donor-set was synthesized. Its reaction with one equivalent of divalent metal perchlorate salts, M(ClO4)(2)center dot 6H(2)O (M = Zn, Cu, and Co), in methanol yielded three mononuclear complexes [ML](ClO4)(2) (M = Zn, 1; Cu, 2; Co, 3) in octahedral geometry. The complexes were fully characterized and their structures were determined using X-ray single crystal diffraction analysis. UV-Vis spectra of the complexes revealed that metal-to-ligand charge transfer (MLCT) transition bands showed readily red-shift in the trend of Zn(II), Co(II), and Cu(II) complexes.
