The organic compound 3,5-dinitrobenzoicacid-4-aminoacetophenone has been synthesized and single crystals were grown successfully by slow evaporation technique using acetone solvent at room temperature. The powder X-ray diffraction study reveals the crystalline nature of the synthesized compound. The FTIR spectral analysis is used to identify the various functional groups present in the grown crystal. The thermal behaviour of the grown crystal has been investigated using Thermogravimetric (TG) and Differential Thermal analyses (DTA). The dielectric studies of the grown crystal have been performed by using conventional parallel plate capacitor method. The variation of dielectric parameters such as dielectric constant, dielectric loss and ac conductivity as a function of temperature and frequency has been studied.
