2-(4-Chloro-benzamido)-acetic acid.

In the crystal structure of the title mol-ecule, C(9)H(8)ClNO(3), adjacent mol-ecules are arranged into centrosymmetric dimers through pairs of inter-molecular O-H⋯O inter-actions. Inter-molecular N-H⋯O hydrogen bonds link the dimers into a layer parallel to the bc plane. In the layer, mol-ecules are packed in a face-to-face π-stacked arrangment, showing π-π stacking inter-actions between the benzene rings with a centroid-centroid distance of 3.6884†(8)†à .
