(E)-N-[(5-Methyl-2-furyl)methylene]-3-nitroaniline
The asymmetric unit of the title compound, C(12)H(10)N(2)O(3), contains two crystallographically independent mol-ecules, in which the furan and benzene rings are oriented at dihedral angles of 46.09 (3) and 39.98 (3)°. In the crystal structure, weak inter-molecular C-H⋯N hydrogen bonds link the mol-ecules into chains running nearly parallel to the a axis.

In the title compound, C(25)H(20)N(2)O(5)S, the benzodioxole ring system is essentially planar [maximum deviation = 0.021 (2) Å] and forms dihedral angles of 85.2 (1) and 74.2 (1)°, respectively, with the formyl benzene and sulfonyl-bound benzene rings. In the crystal, C-H⋯O hydrogen bonds generate C(8) chains along [100] and R(3) (3)(19) ring motifs. In addition, a weak π-π inter-action [centr...

The title Schiff base compound, C(16)H(14)ClN, adopts E configurations with respect to both the C=C and C=N bonds. The dihedral angle between the two aromatic rings is 53.27 (4)°, while the plane through the C=C-C=N system is inclined at 9.06 (8)° to the benzene ring and 44.92 (5)° to the chloro-benzene ring. In the crystal structure, weak C-H⋯Cl and C-H⋯N hydrogen bonds stack the mol-ecules do...

The conformation adopted by the title compound, C20H21N3O3, in the crystal is 'J'-shaped and appears to be at least partially directed by a weak intra-molecular C-H⋯N hydrogen bond. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, forming dimers with R 2 (2)(8) motifs. Furthermore, these dimers connect to each other via C-H⋯O and N-H⋯O hydrogen bonds to form a three-dimensional ne...

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. The dihedral angle between the benzene rings is 45.43 (3)°. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into layers parallel to (010). In addition, there are π-π stacking inter-actions within the layer [centroid-centro...
