Description	Single crystal of an organic material, 4-chloro-4'bromobenzylidene aniline (CBBA), was synthesized and grown by slow evaporation method at room temperature. H-1 and C-13 NMR spectra were recorded to elucidate the molecular structure and functional groups of CBBA were identified using FTIR and FT Raman spectral analyses. The lattice parameters were calculated from single crystal X-ray diffraction data. Single and reasonably sharp peak observed in the high resolution X-ray diffraction curve indicates that the quality of the crystal is good. Thermal properties of CBBA were carried out using thermogravimetric, differential thermal and differential scanning calorimetric analyses and the melting point of the CBBA material is similar to 123 degrees C. The dielectric properties of CBBA crystal was studied as the function of frequency (100 Hz-500 kHz). The optical properties were ascertained by recording UV-vis-NIR and fluorescence spectrum. Further the mechanical properties were studied using Vickers microhardness test.
