摘要：

The salts (L)-arginine.HClO3 and (L)-arginine.HBrO3, were synthesized. The crystals obtained were characterized by IR and NQR spectroscopy, thermal analysis, Nd:YAG laser radiation second harmonic generation, dielectric, piezoelectric and pyroelectric measurements and their crystal structures were determined. (L)-arginine.HClO3 and (L)-arginine.HBrO3 are crystallized in orthorhombic (space group P2(1)2(1)2(1)) and triclinic (space group P1) systems, respectively. Their structures consist of the protonated arginine cation [+(H2N)(2)CNH(CH2)(3)CH(NH3+)COO-] and respective ClO3- or BrO3- anions. Hydrogen bonds (stronger in the bromate) connect anions with cations and the latter with each other. However, these salts have essential distinctions in crystal packing. (c) 2005 Elsevier B.V.
