Growth and characterization of 2-amino-5-nitrobenzophenonium picrate crystals

Abstract

Single crystals of 2-amino-5-nitrobenzophenonium picrate (ANBP) were grown by slow evaporation solution growth technique from a mixed solvent system ethanol-chloroform-acetic acid (1:1:1, v/v). The 1 H and 13 C signals of the grown crystal are identified by the nuclear magnetic resonance analyses. Fourier transformed infrared spectroscopy confirms the presence of characteristic functional groups present in the grown crystal. Powder X-ray diffraction was carried out to determine the structure and crystallinity. The crystal belongs to monoclinic system. The optical properties of the grown crystals were analyzed by UV-Vis spectroscopy. Thermogravimetric and differential thermal analysis studies reveal no decomposition up to the melting point. The surface morphology of the as-grown crystals was studied by scanning electron microscopy.
