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, ?-? 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).

4-Nitro-N-[(E)-thio-phen-2-yl-methyl-idene]aniline.

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 ?-? inter-actions occurring between centrosymmetrically related benzene rings [centroid-centroid distance = 3.6020?(11)?Å].

Methyl 2-meth-oxy-4-{[2-(4-nitro-phen-yl)hydrazinyl-idene]meth-yl}benzoate.

Project description:The mol-ecule of the title Schiff base compound, C(16)H(15)N(3)O(5), obtained from a condensation reaction of 4-acet-oxy-3-meth-oxy-benzaldehyde and 4-nitro-phenyl-hydrazine, adopts an E geometry with respect to the C=N double bond. The mol-ecule is roughly planar, with the two benzene rings twisted slightly with respect to each other by a dihedral angle of 6.90?(9)°. In the crystal, inter-molecular N-H?O hydrogen bonds link centrosymmetrically related pairs of mol-ecules, forming dimers of R(2) (2)(22) graph-set motif. The dimers are further connected through slipped ?-? inter-actions between symmetry-related benzene rings [centroid-centroid distance of 3.646?(1)?Å, offset angle of 15.4°].

Project description:In the title compound, C(15)H(15)N(5)O(4), a nitro-formazan derivative, the formazan unit is essentially planar with an r.m.s. deviation of 0.0204?(6)?Å and adopts a closed syn,s-cis configuration with an intra-molecular N-H?N hydrogen bond.
