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 F2 1 2 1 2 1 with unit cell parameters a = 6.4035(9) Å, b = 11.8835(16) Å, c = 12.3809(17) Å, V = 942.1(2) Å3, Z = 4, Dc = 1.497, Mr = 212.28, μ = 0.523 mm−1, F(000) = 440, R 1 = 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 Å, C···N = 3.354(3) Å 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) Å] along a axis. The title compound was synthesized and characterized by elemental analysis, 1H NMR, 13C NMR, IR, UV–Vis and single crystal XRD.
