Crystal structure of (E)-4-methyl-N-{2-[2-(4-nitrobenzylidene)hydrazin-1-yl]-2-oxoethyl}benzenesulfonamideN,N-dimethylformamide monosolvate

2017

The molecule of the title Schiff base compound, C16H16N4O5S·C3H7NO, displays atransconformation with respect to the C=N double bond. The C—N and N—N bonds are relatively short compared to their normal bond lengths, indicating some degree of delocalization in the molecule. The molecule is bent at the S atom, with an S—N—C—C torsion angle of 164.48 (11)°. The dihedral angle between the two aromatic rings is 84.594 (7)°. Intermolecular N—H...O and C —H...O hydrogen bonds connect centrosymmetrically related molecules into dimers forming rings ofR33(11) andR22(10) graph-set motif stacked along theaaxis into a columnar arrangement. The molecular columns are further linked into a three-dimensional…

Crystal structures of three ortho-substituted N-acylhydrazone derivatives

2017

To explore the effect of the nature of substitutions on the structural parameters and hydrogen-bond interactions inN-acylhydrazone derivatives, the crystal structures of threeortho-substitutedN-acylhydrazone derivatives, namely (E)-N-{2-[2-(2-chlorobenzylidene)hydrazinyl]-2-oxoethyl}-4-methylbenzenesulfonamide, C16H16ClN3O3S (I), (E)-N-{2-[2-(2-methylbenzylidene)hydrazinyl]-2-oxoethyl}-4-methylbenzenesulfonamide, C17H19N3O3S (II), and (E)-N-{2-[2-(2-nitrobenzylidene)hydrazinyl]-2-oxoethyl}-4-methylbenzenesulfonamide, C16H16N4O5S (III), have been determined. The structures of the three compounds display similar molecular conformations and hydrogen-bond patterns. The hydrazone part of the mol…

Crystal structure and Hirshfeld surface analysis of (E)-4-chloro-N-{2-[2-(4-nitro­benzyl­idene)hydrazin-1-yl]-2-oxoeth­yl}benzene­sulfonamide N,N-di­…

2018

Reaction of N-(4-chloro­benzene­sulfon­yl)glycinyl hydrazide with 4-nitro­benzaldehyde gives the N,N-di­methyl­formamide monosolvated N-acyl­hydrazone derivative, (E)-N-{2-[2-(4-nitro­benzyl­idene)- hydrazine-1-yl]-2-oxoeth­yl}-4-χhloro­benzene­sulfonamide. Rings of (10) and (11) graph-set motifs are formed in the crystal structure by N—H⋯O and C—H⋯O hydrogen bonds. The two-dimensional fingerprint (FP) plots for significant inter­molecular inter­actions indicate that the greatest contribution is from the O⋯H/H⋯O contacts (31.3%), corresponding to N⋯H⋯O/C⋯H⋯O inter­actions.
