Crystal structures of three ortho-substituted N-acyl-hydrazone derivatives.

ABSTRACT: To explore the effect of the nature of substitutions on the structural parameters and hydrogen-bond inter-actions in N-acyl-hydrazone derivatives, the crystal structures of three ortho-substituted N-acyl-hydrazone derivatives, namely (E)-N-{2-[2-(2-chloro-benzyl-idene)hydrazin-yl]-2-oxoeth-yl}-4-methyl-benzene-sulfon-amide, C₁₆H₁₆ClN₃O₃S (I), (E)-N-{2-[2-(2-methyl-benzyl-idene)hydrazin-yl]-2-oxoeth-yl}-4-methyl-benzene-sulfonamide, C₁₇H₁₉N₃O₃S (II), and (E)-N-{2-[2-(2-nitro-benzyl-idene)hydrazin-yl]-2-oxoeth-yl}-4-methyl-benzene-sulfonamide, C₁₆H₁₆N₄O₅S (III), have been determined. The structures o
