Abstract:

The title 1:1 adduct, has been prepared and a large single crystal with dimensions of 5 mm×50 mm×20 mm was obtained by slow-cooling method. It produces the green radiation at 532 nm under the irradiation of Nd~3+: YAG laser beam at 1064nm. The crystal structure of this potential non-linear optical material was determined by X-ray diffraction method. The crystal is orthorbombic, space group Pca2_1, with a=2.2701(5) nm, b=0.5852(2) nm, c=0.7815(2) nm, Z=4; final R is 0.054 for 702 observed reflections. The intermolecular hydrogen bonds are formed between the amino and carboxyl groups of glycines, which connect the glycine molecules to form two-dimensional network parallel to the (100) plane, while the intermolecular hydrogen bonds between the carboxyl group of glycine and the carboxyl group of m-nitrobenzoic acid let the latter link to above mentioned two-dimensional network.

Key words: Non-linear optical meterial, Crystal structure, Adduct of glycine and m-mitrobenzoic acid
