Synthesis, crystal structure and spectroscopic characterization of {6-[2-(2-chlorophenyl)-1,3-thiazol-4-yl]-2-oxo-1,3-benzothiazol-3(2H)-yl}acetic acid

摘要

The title compound {6-[2-(2-chlorophenyl)-1,3-thiazol-4-yl]-2-oxo-1,3- benzothiazol-3(2H)-yl}acetic acid was prepared and characterized by elemental analyses, FT-IR, ~1H NMR spectroscopy, X-ray diffraction. A quantum-chemical calculation was performed using the CNDO method. In the title compound, C_(18)H_(11)ClN_2O_3S_2, the crystal structure is stabilized by intermolecular hydrogen bonds (C-H???O=C) to form centrosymmetric R-{2}^{2} (16) dimers and the C-H???O, O-H???N, and C-H???N interactions generating the graph set motifs R-{2}^{2} (9) and R-{2}^{2} (22).
