Abstract

The organic salt of Imidazolium 4-nitrobenzoate (I4NB) has been synthesized and single crystals grown by slow solvent evaporation solution growth technique at room temperature. The 1H and 13C NMR spectra were recorded to confirm the molecular structure of I4NBcrystal. The single crystal XRD analysis shows that both the cation and the anion are interlinked to each other by two types of symmetrical intermolecular hydrogen bonds, namely N(2)-H(2A)···O(3) and N(3)-H(3A)···O(4). The title compound (I4NB) crystallizes in triclinic crystal system with the centro symmetric space group P-1. Fourier transform infrared (FT IR) spectral analysis was used to confirm the presence of various functional groups in the grown crystal. The optical properties were analyzed by the UV-Vis-NIR transmittance and fluorescence emission studies. The thermal stability of the title crystal was investigated by thermogravimetric (TG) and differential thermal analyses (DTA). The surface morphology of the title crystal was studied by scanning electron microscopy
