Crystal structures of Schiff base derivatives of 1-(3,4,5-trimethoxybenzylidene)thiosemicarbazide and (E)-N′-(3-nitrobenzylidene)isonicotinohydrazide

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 plan...

Description
Summary: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–ḦN, O–ḦS and intramolecular C–ḦO 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–ḦN and intramolecular C–ḦO hydrogen bonds.
