Abstract: The title 1: 1:2 adduct has been prepared and a large single crystal with dimensions of 25 mm×40 mm×13 mm was obtained by a slow-cooling method.The crystal gives the green frequency doubling radiation at 532 nm under the irradiation of Nd3+: YAGlaser beam at 1064 nm.The crystal structure of this potential non-linear optical material was studied by X-ray diffraction method.The crystal is triclinic, space group P1, with α=0.5269(1) nm,b=0.8040(1) nm,c=0.9783(2)nm,a=106.14(1)°β=97.27(1)°,r=101.64(1)°,Z=1;R=0.062 for 932 observed reflections, The molecules of L-arginine,maleic acid, and water are connected each other by intermolecular hydrogen bonds to form three-dimensional net-work.

Key words: L-Arginine, Maleic acid, Crystal structure, Non-linear optical
