L-Argininium phosphite – a new candidate for NLO materials

In order to investigate the possibility of salt formation in the L-Arg-H3PO3-H2O system, single crystals of L-argininium phosphite, C6H15N4O2(+)·H2PO3(-), were prepared by evaporation of an aqueous solution containing equimolar quantities of L-arginine and phosphorous acid. The asymmetric unit contains one L-argininium(+) cation and one phosphite [HPO2(OH)](-) anion. The phosphite anions form chains parallel to [010] by O-H...O hydrogen bonding, with an O...O distance of 2.630 (3) Å. The protonated amine and guanidyl groups of the L-argininium(+) cations form N-H...O hydrogen bonds with the carboxylate groups and anions. The IR and Raman spectra are discussed in relation to the crystal structure. The salt displays nonlinear optical (NLO) properties. Another salt was obtained from a solution with a 1:2 molar ratio of components, but was characterized by vibrational spectra only.

“…As observed in 2-amino-5-nitropyridinium hydrogenphosphite (Pecaut & Bagieu-Beucher, 1993), anilinium hydrogenphosphite (Paixã o, Matos Beja, Ramos Silva & Martin-Gil, 2000), 3-ammonium propanoic acid monohydrogenphosphite (Averbuch-Pouchot, 1993b) and diphenylguanidinium monohydrogenphosphite phosphorous-acidwater (Paixã o, Matos Beja, Ramos Silva & Alte da Veiga, 2000), the phosphite groups are hydrogen-bonded in pairs (clusters). In other organic phosphite examples (Averbuch-Pouchot, 1993a,c,d,e;Fleck et al, 2000;Paixã o et al, 2001;Harrison, 2003a,b,c;Mahmoudkhani & Langer, 2001;Harrison, 2004) the phosphite monoanions are linked to form infinite chains, whereas in some organic compounds (Averbuch-Pouchot, 1993f;Idrissi et al, 2002;Bendheif et al, 2003;Gordon & Harrison, 2003) the monoanions are not held together, i.e. no hydrogen bonding occurs between H 2 PO À 3 anions.…”

Crystals of m-carboxyphenylammonium monohydrogenphosphite, C7H8NO2+.H2PO3- (m-CPAMP), space group P2(1)/c, grown from aqueous solution undergo a reversible first-order single-crystal phase transition at Tc = 246 (2) K with a hysteresis of 3.6 K. The thermal behaviour of the sample was characterized by differential scanning calorimetry (DSC) experiments. Variations of the unit-cell parameters versus temperature between 100 and 320 K are reported. The transition from the higher-temperature phase (HTP) to the lower-temperature phase (LTP) is characterized by a unit-cell volume contraction of 1.77%. The average structure and unit-cell packing of m-CPAMP at lower temperature (100 K) are reported from accurate X-ray data sets and compared with those of the higher-temperature phase (293 K) in order to investigate the mechanism of the phase transition. The reciprocal lattice reconstruction showed a few very weak satellite reflections which will be discussed in a forthcoming paper.
