ResumoThe possibility of preparing new analogs of L-arginine phosphate monohydrate, (LAP), has been investigated. Single crystals of the compound L-Arg·HCOOH, which had earlier been obtained in powdered form, were successfully grown during the course of this investigation. In addition, we have found that there is a class of compounds having the Arg·2Ax composition, (where Ax is one of several inorganic or organic acids). Such compounds (Arg·2HIO3, Arg·2HNO3, Arg·2H3PO4, Arg·2HF, Arg·2HCl·H2O, and Arg·2HBr·H2O) have been synthesized and single crystals grown. The crystals grown in this investigation were studied by IR and X-ray diffraction methods. The influence of the different amino acid groups on crystal symmetry and the influence of this symmetry on non-linear optical properties are discussed.
