Project description:In the title compound, C(11)H(8)N(2)O(2)S, there is a twist in the mol-ecule, with the dihedral angle between the five- and six-membered rings being 31.77 (9)°. The nitro group is slightly twisted out of the plane of the benzene ring to which it is attached [O-N-C-C torsion angle = 9.0 (3)°]. The S and N atoms are syn. In the crystal, supra-molecular layers parallel to (-204) are formed by C-H⋯O and C-H⋯N inter-actions. These layers are connected into a three-dimensional architecture by π-π inter-actions occurring between centrosymmetrically related benzene rings [centroid-centroid distance = 3.6020 (11) Å].

4-Meth-oxy-N-[(E)-(5-nitro-thio-phen-2-yl)methyl-idene]aniline.

Project description:The title mol-ecule, C(12)H(10)N(2)O(3)S, is nonplanar with an inter-planar angle of 33.44?(7)° between the benzene and thio-phene rings. In the crystal there exist only weak inter-molecular C-H?O inter-actions, ?-? inter-actions between the benzene rings [centroid-centroid distance = 3.7465?(14)?Å] and X-Y?? inter-actions to the thio-phene and benzene rings [N?centroid distances = 3.718?(3) and 3.355?(3)?Å, respectively]. Inter-molecular C-H?O inter-actions link the mol-ecules into chains parallel to the a axis.

(Z)-3-Meth-oxy-N-[(5-nitro-thio-phen-2-yl)methyl-idene]aniline.

Project description:In the title compound, C(12)H(10)N(2)O(3)S, the dihedral angle between the benzene and thio-phene rings is 43.17 (4)°. The crystal structure is devoid of any hydrogen-bonding inter-actions. However, π-π inter-actions between the benzene and thio-phene rings [distance between ring centroids = 3.6850 (11) Å] stack the mol-ecules along the a axis. The absolute structure could not be determined as the crystal studied was a racemic twin with a BASF parameter of 0.31 (6).

Project description:In the title Schiff-base type compound, C(18)H(13)N(3)O(5), the central furan ring makes dihedral angles of 12.80?(7) and 51.43?(4)° with the terminal benzene rings.

Crystal structure and Hirshfeld surface analysis of 2-methyl-3-nitro-<i>N</i>-[(<i>E</i>)-(5-nitro-thio-phen-2-yl)methyl-idene]aniline.

Project description:The title compound, C12H9N3O4S, synthesized by condensation of 5-nitro-thio-phene-2-carbaldehyde and 2-methyl-3-nitro-aniline, crystallizes in the ortho-rhom-bic space group P212121. In the mol-ecule, the aromatic benzene and thio-phene rings are twisted with respect to each other, making a dihedral angle of 23.16 (7)°. In the crystal, mol-ecules are linked by inter-molecular C-H⋯O hydrogen bonds into chains extending along the c-axis direction. Weak π-π stacking inter-actions along the a-axis direction provide additional stabilization of the crystal structure. The roles of the various inter-molecular inter-actions 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.

Project description:In the title compound, C(17)H(10)Cl(2)N(2)O(3)S, the thio-phene ring and the central benzene ring are almost coplanar [dihedral angle = 8.44?(3)°], while the dihedral angle between the two benzene rings rings is 77.49?(9)°. The crystal packing is stabilized by inter-molecular C-H?O hydrogen bonds.
