Crystal structure and Hirshfeld surface analysis of 2-methyl-3-nitro-N-[(E)-(5-nitro­thio­phen-2-yl)methyl­idene]aniline

The title compound, C(12)H(9)N(3)O(4)S, synthesized by condensation of 5-nitro­thio­phene-2-carbaldehyde and 2-methyl-3-nitro­aniline, crystallizes in the ortho­rhom­bic space group P2(1)2(1)2(1). In the mol­ecule, the aromatic benzene and thio­phene rings are twisted with respect to each other, making a dihedral angle of 23.16 (7)°. In the crystal, mol­ecules are linked by inter­molecular C—H⋯O hydrogen bonds into chains extending along the c-axis direction. Weak π–π stacking inter­actions along the a-axis direction provide additional stabilization of the crystal structure. The roles of the various inter­molecular inter­actions were clarified by Hirshfeld surface analysis, which reveals that the crystal packing is dominated by O⋯H (39%) and H⋯H (21.3%) contacts. The crystal studied was refined as a two-component inversion twin.
