Crystal structure of 1,3-dihydroxy-2-(hydroxymethyl)propan-2-aminium 2-(4-isobutylphenyl)propanoate: a simple organic salt of racemic ibuprofen
نویسنده
چکیده
In the title organic salt of ibuprofen with trometamol, C4H12NO3 (+)·C13H17O2 (-), the carb-oxy-lic 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 propano-ate 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.
