Methyl 3-[(E,E)-3-phenyl-prop-2-enyl-idene]dithio-carbazate.

ABSTRACT: In the title compound, C(11)H(12)N(2)S(2), the dithio-carbazate group adopts an EE configuration with respect to the C=C and C=N bonds of the propenyl-idene group. The atoms of the propenyl-idene and dithio-carbazate unit are essentially co-planar, with a maximum deviation of 0.058 (1) Å; the phenyl ring forms a dihedral angle of 18.3 (1)° with this fragment. In the crystal, mol-ecules form inversion dimers via pairs of N-H⋯S hydrogen bonds involving the terminal S atom.

Benzyl 3-[(E,E)-3-phenyl-prop-2-enyl-idene]dithio-carbazate.

Project description:The title compound, C(17)H(16)N(2)S(2), a dithio-carbazate derivative, adopts an EE configuration with respect to the C=C and C=N double bonds of the propenyl-idine group. The 3-phenyl-prop-2-enyl-idene and dithio-carbazate fragments lie essentially in the same plane, with a maximum deviation from that plane of 0.074?(2)?Å, while the dihedral angle between the 3-phenyl-prop-2-enyl-idene and the benzyl group is 77.78?(7)°. In the crystal structure, mol-ecules are linked by an N-H?S hydrogen bond and a weak C-H?S inter-action involving the terminal thione S atom, forming dimers that are arranged into sheets parallel to the bc plane. The crystal structure is also stabilized by C-H?? inter-actions.

Methyl 3-[(E)-furfuryl-idene]dithio-carbazate.

Project description:The mol-ecule of the title Schiff base compound, C(7)H(8)N(2)OS(2), prepared by the reaction of methyl dithio-carbazate and furfural in an ethanol solution under reflux, adopts an E configuration; the dithio-carbazate and furan units are located on opposite sides of the C=N double bond.

Adjacent mol-ecules are linked by N-H?S hydrogen bonding to form a supra-molecular dimer across an inversion center.

Project description:In the title compound, [Hg(C(17)H(15)N(2)S(2))(2)], the Hg(II) ion lies on a crystallographic twofold rotation axis giving a very distorted tetra-hedral coordination geometry best described as bis-phenoidal, being chelated by two deprotonated N,S Schiff base ligands through the azomethine nitro-gen and the thiol-ate sulfur donors.

(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.
