thiosemicarbazones 1–4, respectively. 1–4 were characterized by elemental analysis (CHN), FTIR, and 1H and 13C1H} NMR spectroscopy. In addition, the crystal structures of 2 and 3 were determined by single-crystal X-ray diffraction. Our X-ray structural results have shown that the nitropiperonal and thiosemicarbazone moieties exhibit an almost coplanar arrangement for both 2 and 3. Moreover, they establish
