Synthesis and crystal structures of ( E )- N '-(4-chloro-3-nitro-benzyl-idene)acetohydrazide and ( E )-2-(4-chloro-benzyl-idene)-1-(quinolin-8-yl)hydrazine.

The syntheses of two benzyl-idenehydrazine derivatives, namely, ( E )- N '-(4-chloro-3-nitro-benzyl-idene)acetohydrazide, C 9 H 8 ClN 3 O 3 , and ( E )-2-(4-chloro-benzyl-idene)-1-(quinolin-8-yl)hydrazine, C 16 H 12 ClN 3 , are reported. The mol-ecules have been characterized using IR, 1 H NMR, 13 C NMR and mass spectro-scopic and elemental analysis techniques, and their structures have been determined by single-crystal X-ray diffraction.
