Syntheses and crystal structures of hydrated and anhydrous 1:2 cocrystals of oxyresveratrol and zwitterionic proline.

ABSTRACT: The hydrated and anhydrous 1:2 cocrystals of oxyresveratrol (4-[(E)-2-(3,5-di-hydroxy-phen-yl)ethen-yl]benzene-1,3-diol; OXY; C₁₄H₁₂O₄) and proline [(S)-pyrrolidine-2-carb-oxy-lic acid; PRO; C₅H₉NO₂], namely, 4-[(E)-2-(3,5-di-hydroxy-phen-yl)ethen-yl]benzene-1,3-diol bis-[(S)-pyrrolidin-1-ium-2-carboxyl-ate] monohydrate, C₁₄H₁₂O₄·2C₅H₉NO₂·H₂O, and the anhydrous form, C₁₄H₁₂O₄·2C₅H₉NO₂, were obtained by crystallization at different temperatures. Both of them crystallize with ortho-rhom-bic (P2₁2₁2₁) symmetry. The struc
