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.
