(E)-Methyl 3-(2-nitro-benzyl-idene)dithio-carbazate.

Project description:The asymmetric unit of the title compound, C(9)H(9)N(3)O(2)S(2), contains two independent mol-ecules, A and B, with similar bond dimensions. In both mol-ecules, the nitro group is tilted with respect to the aromatic ring [dihedral angles 32.0?(1)° in mol-ecule A and 34.0?(1)° in mol-ecule B]. The dithio-carbazate unit is nearly coplanar with the aromatic ring in both mol-ecules. For mol-ecule B, pairs of mol-ecules are linked by N-H?O and C-H?O hydrogen bonds about a centre of symmetry to form a dimer, whereas mol-ecules A are not involved in hydrogen bonding in the crystal structure.

Project description:In the title compound, C(14)H(14)N(2)S(3), the thione S atom and methyl group are syn, as are the two thio-ether S atoms. The mol-ecule is twisted, the dihedral angles between the central (C(2)N(2)S(2)) residue and the pendent 2-thienyl and phenyl rings being 21.57?(6) and 77.54?(3)°, respectively.

Project description:The title compound, C(16)H(16)N(2)S(2), was obtained from the condensation reaction of benzyl dithio-carbazate and 2-methyl-benzaldehyde.

In each mol-ecule, the dithio-carbazate fragment is approximately planar, the r.m.s deviations being 0.018 and 0.025?Å. The mean plane of dithio-carbazate group is oriented at dihedral angles of 7.9?(3) and 68.24?(12)°, respectively, to the methyl-phenyl and phenyl rings in one mol-ecule, while the corresponding angles in the other mol-ecule are 10.9?(3) and 69.76?(16)°. Inter-molecular N-H?S hydrogen bonding occurs in the crystal structure to generate inversion dimers for both molecules.
