Publication date 2007/10/1 Journal Optics communications Volume 278 Issue 1 Pages 180-186 Publisher North-Holland Description

Single crystals of a new hybrid compound salt: 2-methoxyanilinium nitrate were prepared by slow evaporation at room temperature of diluted aqueous solutions containing 2-methoxyaniline with nitric acids. The compound crystallizes in a space group Pcab of orthorhombic system with cell

parameters a = 8.8784 (6) Å, b = 10.6348 (7) Å, c = 18.3045 (7) Å, V = 1728.31 (17) Å3 at T = 100 K

and Z = 8. The structure has been refined to an R-value of 0.044 for 1956 observed reflections using

three-dimensional X-ray diffraction data. Third-order nonlinear optical susceptibility (χ<3>) was

measured by degenerate four wave mixing (DFWM) method at 532 nm. Third harmonic generation (THG) measurements at the 1064 nm were carried out for the 2-methoxyanilinium nitrate crystal with the following dimensions: 4 × 9 × 0.5 mm.
