4-(Methylamino)benzoic acid
The asymmetric unit of the title compound, C(8)H(9)NO(2), 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) Å from the mean plane through the non-H atoms. In the crystal, all three molecules...

| Sumario: | The asymmetric unit of the title compound, C(8)H(9)NO(2), 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) Å from the mean plane through the non-H atoms. In the crystal, all three molecules form O—H⋯O hydrogen-bonded about inversion centers, forming eight-membered rings with graph-set notation R (2) (2)(8). In addition, N—H⋯O hydrogen bonding and C—H⋯π interactions reinforce the packing. |
