Özet

The asymmetric unit of the title compound, C8H9NO2, contains three crystallographically independent molecules, which are essentially planar, the carboxyl O atoms deviating by 0.091 (3), 0.101 (2) and 0.164 (3) angstrom from the mean plane through the non-H atoms. In the crystal, all three molecules form O-H center dot center dot center dot O hydrogen-bonded about inversion centers, forming eight-membered rings with graph-set notation R-2(2)(8). In addition, N-H center dot center dot center dot O hydrogen bonding and C-H center dot center dot center dot pi interactions reinforce the packing.
