Synthesis, Spectral, and Structural Characterization of Bisthiocarbohydrazone Derivatives
2013
Abstract Bisthiocarbohydrazone derivatives of three heterocyclic ketone ligands, having a flexible coordination ability; 1, 5-bis (2-acetylthiophene) thiocarbohydrazone; 1, 5-bis (2-acetylfuran) thiocarbohydrazone; and 1, 5-bis (2-acetylpyrrole) thiocarbohydrazone were synthesized and characterized by elemental analysis, UV-visible, FT-IR, cyclic voltammetry, and 1H and 13C-NMR spectral studies. All bisthiocarbohydrazone exhibited the thioketone—thioenol tautomeric forms, as evidenced by IR spectral data and single crystal X-ray diffraction studies of 1, 5-bis (2-acetylfuran) thiocarbohydrazone and 1, 5–bis (2-acetylpyrrole) thiocarbohydrazone.
