(R)-Methioninium–(R)-mandelate–(R)-mandelic acid (1/1/2)

Abstract

The title mol­ecular complex, C5H12NO2S+·C8H7O3−·2C8H8O3, contains (R)-methio­ninium cations, (R)-mandelate anions and (R)-mandelic acid mol­ecules. The (R)-methio­ninium cation assumes an anti conformation for all of its single bonds. Hydro­philic and hydro­phobic layers alternate in the crystal structure. Hydrogen-bond inter­actions and van der Waals contacts occur in the hydro­philic and hydro­phobic layers, respectively.
