A New 2-((Z)-Thiosemicarbazidomethyl)- Quinolin-8-YL Acetate Ligand and its Cu(II) Complex: Syntheses,Structures, and Characterizations

Abstract

A new ligand, 2-((Z)-thiosemicarbazidomethyl)-quinolin-8-yl acetate (C₁₃H₁₂ N₄O₂S) (L) and its Cu(II) coordination complex, [Cu(L₁)] [HL₁ = (Z)-1-((8-hyd- roxyquinolin-2-yl)methylene)thiosemicarbazide], have been synthesized, and characterized by IR, elemental analysis, ¹H NMR, MS, and X-ray single-crystal diffraction. L shows a stable three-dimensional supramolecular structure through hydrogen bonds and π-π stacking interactions. [Cu(L₁)] shows a three-dimensional network structure formed only by hydrogen bonds. In addition, the fluorescence spectra of L were measured.
