摘要

SYNTHESIS AND STRUCTURAL CHARACTERIZATION OF THE LIGAND ISATIN-3-(N-4-BENZYLTHIOSEMICARBAZONE) AND ITS MERCURY(II) COMPLEX. The reaction of 4-(phenyl) thiosemicarbazide with isatin yielded a new ligand, isatin-3-(N-4-benzylthiosemicarbazone). Isatin-3-(N-4-benzylthiosemicarbazone) deprotonated in ethanol/KOH reacts with an ethanolic solution of Hg(NO3)(2) to give a mercury complex. The compounds were characterized by IR and X-ray single crystal structure determination. The X-ray studies revealed that the complex possesses a tetrahedral geometry with two deprotonated thiosemicarbazone ligands coordenated. The ligand and its mercury complex crystallize in the monoclinic (P2(1)/c) and triclinic (P-1) crystal system, respectively.
