Abstract: | A thiosemicarbazone derivative, 2‐acetylpyridine 4‐phenylthiosemicarbazone, was prepared and complexed to Lewis acids, Sn(CH3)2X2, X = Cl and Br. The products, SnX(C14H13N4S)(CH3)2], were characterized by single‐crystal X‐ray diffraction, and IR, NMR and Mössbauer spectroscopies. They are isomorphous and crystallize in the monoclinic space group P21/n. The structure determination revealed discrete neutral complexes with the SnIV atom in a distorted octahedral coordination geometry, with the halogeno ligand and the thiosemicarbazone derivative in the equatorial plane and the methyl groups in axial positions. |
