Crystal structure of 1,3-dihydroxy-2-(hydroxymethyl)propan-2-aminium 2-(4-isobutylphenyl)propanoate: a simple organic salt of racemic ibuprofen

Abstract

The title compound is an organic salt of ibuprofen with trometamol, in which the carb­oxy­lic acid group of ibuprofen has transferred its proton to the amine N atom of trometamol. In the crystal, the ions are linked by a series of O—H⋯O and N—H⋯O hydrogen bonds, forming sheets parallel to (100).
