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

The mol­ecule of the title Schiff base compound, C16H16N4O5S·C3H7NO, displays a trans conformation 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 of R33(11) and R22(10) graph-set motif stacked along the a axis into a columnar arrangement. The mol­ecular columns are further linked into a three-dimensional network by C—H⋯π inter­actions.
