- Abstract
ß-Alaninium picrate crystallizes in the form of yellow columns, in the triclinic system (space group PView the MathML source, Z = 2). The asymmetric unit contains one ß-alaninium cation and one picrate anion. Nevertheless, the unit cell comprises a dimeric centrosymmetric ß-Ala+?ß-Ala+ cation and two picrate anions. The O?O distance (2.636(2) Å) in the dimeric cation is among the shortest distances of known salts with A+?A+ type dimeric cations. The infrared and Raman spectra are shown and discussed. A comparison of known crystals with ß-Ala+?ß-Ala+ cations is presented, which shows that four different types can be distinguished.
