N-Et quinolinium chromophore crystal 2-[2-(4-chloro-phenyl)-vinyl]-1-ethyl-quinolinium iodide (I·I) was successfully grown by the slow evaporation technique. Single crystal X-ray diffraction studies revealed that I·I crystallized in the monoclinic crystal system with the centrosym. space group C2/c. The mol. formation of the grown crystal was initially identified using 1H NMR and FTIR anal. The linear optical studies of crystal I·I were done by UV-vis-NIR studies and thermal studies revealed the stability till its m.p. at 239.7 °C. The grown crystal of I·I exhibited high third order optical nonlinearity which was determined by the Z-scan technique.
