Abstract

Recently, we have discovered a new class of salts containing different amino acids. In the present paper, we report crystal structures of four types ([A(1)H][A(2)H]Y, A(1)H[A(2)H···A(2)]Y, A(1)H[A(1)H···A(2)]Y and [A(1)H···A(2)]2Y) of salts containing a hexafluorosilicate anion (Y is SiF62−) and amino acids glycine, sarcosine, dimethylglycine, betaine, β-alanine, and L-proline: (β-AlaH)(BetH)SiF6·H2O (I), (β-AlaH)(L-ProH)SiF6 (II), (β-AlaH)(L-ProH···L-Pro)SiF6 (III), (BetH)(BetH···Sar)SiF6·H2O (IV), (GlyH···DMG)2SiF6 (V), and (DMGH···Sar)2SiF6 (VI). The O⋅⋅⋅O distances in dimeric cations (L-ProH···L-Pro), (BetH···Sar), (GlyH···DMG), and (DMGH···Sar) are 2.439 (3), 2.5310 (12), 2.4979 (9), and 2.4612 (19) Å in (III), (IV), (V), and (VI), respectively.
