Background and Objective: The crystal structure of 7’-Nitro-6’-phenyl-1’,6’,7’,7a’-tetrahydro-spiro[indeno[1,2-b]quinoxaline-11,5’-pyrrolo[1,2-c][1,3]thiazole](NPTSIPT) crystal was recently reported by authors group. The main objective of the present study was to analyze the vibrational spectra of title compound. So it was crystallized by slow evaporation method and characterized by the single crystal XRD, FT-IR, FT-Raman and UV-Visible spectroscopy analysis. Materials and Methods: The raw materials used for this crystallization are benzene-1, 2-diamine, 1H-indene-1, 2, 3-trione, thiazolidine-4-carboxylic acid, methanol, chloroform and trans-β-nitro styrene which were purchased from Sigma Aldrich Company through local scientific companies in Tamil Nadu, India. The crystals were obtained by the slow evaporation method using the chloroform as a solvent. Results: Using X-ray diffractometer, the unit cell parameters and space group of title crystal was obtained. The FT-IR and FT-Raman spectroscopic techniques have been used to identify the vibrational modes of compound. The optical property was analyzed by UV-Visible spectroscopy. Conclusion: The single crystal XRD study revealed that the title compound belongs to triclinic crystal system with centro symmetric space group P1̄. The vibrational spectra have been investigated by FT-IR, FT- Raman spectroscopic techniques to elucidate the various functional groups present in the molecule. The optical property was analyzed by UV-Visible spectroscopy which showed that the grown crystal has high transparency in the entire visible region. Due to the wide variety of biomedical applications in biological and pharmaceutical fields, the modified quinoxaline structure of title compound is considered for study in this present research.
