  A novel organic optical material 4-chloro -N- methyl 4-stilbazolium besylate, a new derivative of the stilbazolium tosylate family has been synthesized and good optical quality single crystals of size 15 mm x 8 mm x 5 mm were grown by slow cooling technique. The grown crystals were subjected to different instrumentation methods for characterization. The crystal system and lattice parameters were found from single crystal X-ray diffraction. The crystalline perfection is quite good as observed from the high resolution X-ray diffractometry. Fourier transform infrared was recorded to confirm the functional groups. Thermal analyses have been made and the sample has been found to be thermally stable upto 190 ºC. The results are discussed in detailed.
