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

ABSTRACT: In the title compound, C(13)H(12)N(2)OS(2), the mol-ecule assumes an E configuration, with the furan ring and dithio-carbazate units located on opposite sides of the N=C double bond. In the crystal structure, mol-ecules are linked via two inter-molecular N-H?S hydrogen bonds to form centrosymmetric dimers.

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. The planar dithio-carbazate group is twisted slightly with respect to the furan ring, making a dihedral angle of 5.2?(1)°. Adjacent mol-ecules are linked by N-H?S hydrogen bonding to form a supra-molecular dimer across an inversion center.

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.
