<i>rac</i>-<i>tert</i>-Butyl{2-hydroxy-2-[4-hydroxy-3-(hydroxymethyl)phenyl]ethyl}azanium acrylate

The title salt, C13H22NO3+·C3H3O2−, comprises one salbutamol cation and an acrylate anion. The acrylate anion is linked to the salbutamol cationviaan O—H...O and an N—H...O hydrogen bond. The C=C group of the acrylate anion is disordered over two positions, with refined site occupancies of 0.812 (7) and 0.188 (7). The crystal structure is stabilized by N—H...O and O—H...O hydrogen-bonding interactions.
