In the title compound, C 21 H 18 N 4 O 5 , the central vanillin group makes dihedral angles of 8.76 (13) and 62.38 (6) with its attached pyridine and nitrobenzene rings, respectively. The crystal packing is stabilized by N-HÁ Á ÁN hydrogen bonds and C-HÁ Á ÁO interactions, leading to an infinite net
In the title compound, C 22 H 20 N 4 O 5 , the central vanillin group makes dihedral angles of 4.44 (11) and 60.33 (6) with the pyridine and other benzene rings. The crystal packing is stabilized by N-HÁ Á ÁN hydrogen bonds and C-HÁ Á ÁO interactions, leading to an infinite network.
Reaction of toluene-4-sulfonohydrazide with 4-methylbenzaldehyde resulted in the formation of the imine title compound, C 15 H 16 N 2 O 2 S. In the crystal structure, molecules are linked into chains through intermolecular N-HÁ Á ÁO hydrogen-bond interactions.
