3-(2-Pyridylaminocarbonyl)propanoic acid
In the crystal structure of the title compound, C(9)H(10)N(2)O(3), the mol-ecules are linked by inter-molecular O-H⋯N and N-H⋯O hydrogen bonds, resulting in chains propagating in [010]. Weak intra-molecular and inter-molecular C-H⋯O inter-actions are also observed.

In the title compound, C(9)H(10)O(4), the carboxyl group is oriented at a dihedral angle of 84.6 (3)° with respect to the benzene ring. In the crystal, mol-ecules are linked via O-H⋯O hydrogen bonds.
متن کامل3-(2-Formylphenoxy)propanoic acid
In the structure of the title compound, C(10)H(10)O(4), the carboxyl group forms a catemer motif in the [100] direction instead of the expected dimeric structures. The carboxylic acid group is found in the syn conformation and the three-dimensional organization in the crystal is based on C-H⋯O and O-H⋯O interactions.
متن کامل3-(2-Acetylanilino)propanoic acid
The title mol-ecule, C(11)H(13)NO(3), has its propanoic acid group in an extended conformation, such that the mol-ecule is nearly planar, with a mean deviation of 0.036 Å [the maxima being 0.106 (1) and 0.110 (1) Å for the two methyl-ene C atoms]. The NH group forms an intra-molecular hydrogen bond with the acetyl group; in the crystal COOH group forms a centrosymmetric hydrogen-bonded dimer.
متن کامل3-(2-Fluorophenoxy)propanoic acid
In the title compound, C(9)H(9)FO(3), the dihedral angle between the carboxyl group and the benzene ring is 79.4 (3)°. In the crystal, mol-ecules form centrosymmetric dimers through pairs of classical O-H⋯O hydrogen bonds. These are further linked by weaker C-H⋯O inter-actions, forming a three-dimensional network.
