The structures of two brucinium (2,3-dimeth�y-10-oxostrychnidinium) salts of the a-hydr�y acids l-malic acid and l-tartaric acid, namely brucinium hydrogen (S)-malate penta�drate, C23H27N2O4+烴H5O5-絈2O, (I), and anhydrous brucinium hydrogen (2R,3R)-tartrate, C23H27N2O4+烴H5O6-,(II), have been determined at 130 K. Compound (I) has two brucinium cations, two hydrogen malate anions and ten water mol�ules of solvation in the asymmetric unit, and forms an extensively hydrogen-bonded three-dimensional framework structure. In compound (II), the brucinium cations form the common undulating brucine sheet substructures, which accommodate ...

In compound (II), the brucinium cations form the common undulating brucine sheet substructures, which accommodate parallel chains of head-to-tail hydrogen-bonded tartrate anion species in the inter�itial cavities.
