Molecules of (cyclohexylideneamino)oxyacetic acid, C 8 H 13 NO 3 , (I), are linked into centrosymmetric dimers by pairs of O—H⋯O hydrogen bonds [H⋯O = 1.84 Å, O⋯O = 2.6782 (12) Å and O—H⋯O = 178°]. In [chloro(phenyl)methyleneamino]oxyacetic acid, C 9 H 8 ClNO 3 , (II), the molecules are similarly linked into centrosymmetric dimers by pairs of O—H⋯O hydrogen bonds [H⋯O = 1.79 Å, O⋯O = 2.6329 (17) Å and O—H⋯O = 176°], and these dimers are weakly linked into chains by a single type of aromatic π–π stacking interaction.
