- Abstract
In the present paper, we report crystal structures of four types ([A(1)H][A(2)H]Y, [A(1)H]3[A(2)H]Y2, A(1)H[A(2)H···A(2)]Y, and A(1)H[A(1)H···A(2)]Y) of mixed salts containing the sulfate anion (Y = SO42− ) and amino acids A, i.e., sarcosine (Sar), dimethylglycine (DMG), betaine (Bet), β-alanine (β-Ala), and L-roline (L-Pro): (β-AlaH)(DMGH)SO4·2H2O (I), (β-AlaH)(BetH)SO4 (II), (β-AlaH)(L-ProH)SO4 (III), (BetH)(L-ProH)SO4 (IV), (SarH)3 (L-ProH)(SO 4 )2(V), (β-AlaH)(L-ProH···L-Pro)SO4 (VI), and (β-AlaH)(β-AlaH···DMG)SO4(VII). The O···O distances in dimeric cations (L-ProH···L-Pro) and (β-AlaH···DMG) are 2.450(3) and 2.5295(12) Å in (VI) and (VII), respectively. Crystal structure determinations of (β-AlaH)(BetH)SO4(II) at 100 K (P21 /n), 200 K (Pnma), 250 K (Pnma), and room temperature (Pnma) revealed a structural phase transition in the interval between 100 and 200 K.
