4-[(1,3-Dioxo-2,3-dihydro-1H-benzo[de]isoquinolin-2-yl)methyl]-N′-[(E)-4-nitrobenzylidene]benzenesulfonohydrazide dimethyl sulfoxide monosolvate

Abstract

The mol­ecular structure of the title compound, C26H18N4O6S·C2H6OS, shows an E conformation of the hydrazone double bond. The presence of a methyl­ene group between the benzo[de]isoquinoline and benzene­sulfonyl moieties allows the 4-nitro­phenyl ring and the benzo[de]isoquinoline system to be parallel with respect to each other, so that the mol­ecule adopts a U-shaped spatial conformation. The dihedral angle between mean planes of these aromatic groups is 4.4 (1)°. This special arrangement enables neighboring mol­ecules to be inter­calated, forming slipped π–π inter­actions [centroid–centroid distance = 3.535 (2) Å] between the 4-nitro­phenyl and benzo[de]isoquinoline groups and point-to-face C—H⋯π inter­actions between the benzo[de]isoquinoline and benzene­sulfonyl aromatic systems. In addition, the crystal packing also features an inter­molecular N—H⋯O inter­action involving the amine group and the dimethyl sulfoxide solvent mol­ecule.
