In the title compound, C14H16N2O3, an analog of the chromophore in green fluorescent protein, the methoxyphenyl substituent and the imidazole N adopt a Z conformation with respect to the C=C bond. Aside from the hydroxyethyl group, the molecule is approximately planar, with the five- and six-membered ring planes forming a dihedral angle of 9.3 (1)°. An intramolecular C—H
N contact occurs. In the crystal, O—HN hydrogen bonds link the molecules, forming chains along the b-axis direction. C—HO hydrogen bonds are also observed.

In the title compound, C19H22N2, both the benzimidazole unit and the 2,6-diisopropylphenyl group are essentially planar [maximum deviations from the least-squares planes of 0.005 (1) and 0.009 (1) Å, respectively]. The dihedral angle between the two planes is 79.6 (7)°. In the crystal, molecules are linked into chains along the a-axis direction by weak C—HN interactions. The crystal structure also features C—Hπ interactions, which link the chains into a three-dimensional network.

In the title compound, C14H12N2O3, the pyridine ring is twisted with respect to the phenyl ring and the carboxylic acid group at angles of 37.1 (5) and 8.1 (3)°, respectively; the phenyl ring forms a dihedral angle of 41.4 (1)° with the mean plane of the C—NH—C=O fragment. An intramolecular O—HO hydrogen bond occurs between the carboxylic acid and carbonyl groups. In the crystal, N—HO hydrogen bonds link molecules into a supramolecular chain running along the a-axis direction.
