title: β-Alaninium tetrafluoroborate: a new salt with di-β-alaninium dimeric cation.
abstract: β-Alaninium tetrafluoroborate crystallizes in the monoclinic system (space group P21/n, Z=4). The asymmetric unit contains one β-alaninium cation and one tetrafluoroborate anion, in which the fluorine atoms are disordered. All β-alaninium cations are connected with the symmetry related cations via an inversion center, thus forming dimeric centrosymmetric β-Ala(+)···β-Ala(+) cations. The O···O distance (2.698(2)Å) in the dimeric cation is relatively long compared to known distances of previously reported salts with A(+)···A(+) type dimeric cations. The infrared and Raman spectra are studied.
