The crystal structures of 1-(3,4,5-trimethoxybenzylidene)thiosemicarbazide (1) and N�-(3-nitrobenzylidene) isonicotinohydrazide (2) have been determined by single-crystal X-ray diffraction. In compound 1, the position of C8, O1, O2, O3 atoms are in a distorted trigonal planar geometry. The mean plane of 3,4,5-trimethoxybenzylidene ring forms a dihedral angle of 5.39(14)° with the mean plane of thiosemicarbazide group. In the structure, the molecular packing is stabilized by intermolecular N-?N, O-?S and intramolecular C-?O hydrogen bonds. In compound 2, the position of C8 atom and N1 atom are in a distorted trigonal planar geometry. The mean plane of phenyl ring forms a dihedral angle of 8.09° with that of the pyridine ring. In the structure, the molecular packing is stabilized by intermolecular N-?N and intramolecular C-?O hydrogen bonds. © 2014 AIP Publishing LLC.
