【 摘 要 】

In the title organic salt of ibuprofen with trometamol, C4H12NO3+·C13H17O2−, the carb­oxy­lic acid group of ibuprofen has transferred its proton to the amino N atom of trometamol. In the crystal, the trometamol cations are linked via N—H⋯O hydrogen bonds, forming chains along [001]. To these chains are attached the ibuprofen anions via O—H⋯O and N—H⋯O hydrogen bonds. The chains are linked via further N—H⋯O and O—H⋯O hydrogen bonds, forming sheets parallel to (100). Two C atoms of the propano­ate substituent in the ibuprofen anion are disordered over two sets of sites and were refined with a fixed occupancy ratio of 0.7:0.3.
