- Abstract
The mixed salts of L-lysinium(2+) chloride nitrate (I), L-lysinium(2+) chloride tetrafluoroborate (II) andL-lysinium(2+) chloride perchlorate (III) have been obtained from aqueous solution and their crystalstructures have been determined. All three crystals crystallize in the monoclinic system (space groupP21), (II) and (III) are even isostructural. The asymmetric unit of (I) contains one formula unit(L-Lys2+.Cl.NO3- ), in contrast to the asymmetric units of (II) and (III) which contain two formula unitsof (L-Lys2+.Cl.BF4-) and (L-Lys2+.Cl.ClO4- ). The L-Lys2+ cations in the structures have similarly extendedconformation, although there is a difference: In (I), the a-carbon is in gauche and the NH3-group in transposition, in (II) and (III) it is the other way round. The crystals are stabilized by an extensive network ofOAH...Cl, NAH...Cl, and NAH...O, NAH...F hydrogen bonds. ATR FTIR and Raman spectra of the salts havebeen registered and are discussed.
