The reaction of 4-phenylthiosemicarbazide with p-dimethylaminobenzaldehyde produced 1-[4-(dimethylamino)benzylidene]-4-phenylthiosemicarbazide which was characterized by elemental analy-sis, IR, UV, 1H NMR and XRD. The crystal belongs to orthorhombic system with space group P212121 and a=0.77038(14) nm, b=1.1428(2) nm, c=1.6726 nm, V=1.4726(5) nm3, Z=4, Dc=1.346 g/cm3, F(000)=632, μ=0.219 mm-1, the final R=0.0407 and wR=0.1157 for 2807 observed reflections [I>2σ(I)]. The crystal structure and the solid-state circular dichroism spectrum showed that an enantiomer of the compound packs into the chiral crystal.

Key words: synthesis, chiral crystal structure, circular dichroism spectrum, 1-[4-(dimethylamino)benzylidene]-4-phenylthiosemicarbazide
