Abstrakt:	A thio­semicarbazone derivative, 2-acetyl­pyridine 4-phenyl­thio­semicarbazone, was prepared and complexed to Lewis acids, Sn(CH3)2 X2, X = Cl and Br. The products, [Sn X(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.
