Synthesis and Characterization of (Z)-Furan-2-carbaldehyde Thiosemicarbazone at Low Temperature

Abstract

The compound, C₆H₇N₃OS, has been prepared and characterized by condensation between thiosemicarbazide and furan-2-carbaldehyde and its structure was elucidated by x-ray analysis (at 150 K), NMR and IR spectroscopy methods (at ambient temperature). It crystallizes in the monoclinic space group P2₁/c (No. 14), a = 13.5099(3) Å, b = 5.67430(10) Å, c = 23.4755(6) Å, β= 117.367(2)°, V = 1598.20(7) ų and Z = 8. The crystal structure was solved and refined to R = 0.0290 with 2942 unique reflections. No significant π-π interactions are found in the crystal structure. There are C-H…π interactions and also different weak hydrogen bonds, stabilizing the three dimensional crystal structure.
