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

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, H-1 NMR spectroscopy, X-ray diffraction. A quantum-chemical calculation was performed using the CNDO method. In the title compound, C18H11ClN2O3S2, the crystal structure is stabilized by intermolecular hydrogen bonds (C-H center dot center dot center dot O=C) to form centrosymmetric R-2(2)(16) dimers and the C-H center dot center dot center dot O, O-H center dot center dot center dot N, and C-H center dot center dot center dot N interactions generating the graph set motifs R-2(2)(9) and R-2(2)(22).
