The title compound, N-1, 3-Dithiolan-2-ylidene-N′-[1-furan-2-yl-meth- (E)-ylidene]-hydrazine was synthesized via furfural with 2-hydrazono-1, 3-dithiolane and characterized by elemental analysis, 1H NMR, 13C NMR, IR, UV-Vis and single crystal XRD. The crystal belongs to orthorhombic, space group F212121 with unit cell parameters a = 6.4035(9) A, b = 11.8835(16) A, c = 12.3809(17) A, V = 942.1(2) A3, Z = 4, Dc = 1.497, Mr = 212.28, μ = 0.523 mm-1, F(000) = 440, R1 = 0.0243, and wR 2 = 0.0602. The molecule is the anti-rotamer of the trans-isomer and every molecule forms zig-zag C(7) chains via C-H...N inter-molecular hydrogen-bond [H...N = 2.74 A, C...N = 3.354(3) A and C-H...N = 142°] running parallel to the [010] direction. At the same time many molecules self-assemble the left-handed spiral C(7) chains and inverse ones via the S...O short contacts [S...O = 3.1867(13) A] along a axis.
