Methyl 3-(4-methyl­benzyl­idene)carbazate

The title compound, C₁₀H₁₂N₂O₂, was prepared by the reaction of methyl carbazate and 4-methyl­benzaldehyde. The dihedral angle between the benzene ring and the carbazate fragment is 20.86 (10)°. In the crystal structure, mol­ecules are linked by inter­molecular N—H...O hydrogen bonds.

N′-(4-Cyano­benzyl­idene)thio­phene-2-carbohydrazide

The title compound, C₁₃H₉N₃OS, was prepared by the reaction of thio­phene-2-carbohydrazide and 4-formyl­benzonitrile. The dihedral angle between the benzene and thio­phene rings is 11.9 (1)°. In the crystal structure, mol­ecules are linked into centrosymmetric dimers by pairs of N—H...O hydrogen bonds.
