Diethyl 3,3′-(phenyl­methyl­ene)bis­(1H-indole-2-carboxyl­ate)

In the title compound, C₂₉H₂₆N₂O₄, the benzene ring is twisted by 73.5 (5) and 84.9 (3)° with respect to the mean planes of the two indole ring systems; the mean planes of the indole ring systems are oriented at a dihedral angle of 82.0 (5)°. In the crystal, mol­ecules are linked by pairs of N—H...O hydrogen bonds into chains.

N-[(2S)-2-Chloro­propano­yl]glycine

The title compound, C₅H₈ClNO₃, was prepared by the nucleophilic substitution reaction of (2S)-2-chloro­propanoyl chloride with glycine. The acetate group forms a dihedral angle of 84.6 (1)° with the mean plane of the C—NH—C=O fragment. In the crystal, the molecules are linked by N—H...O and O—H...O hydrogen bonds, generating a three-dimensional network, which consolidates the crystal packing.
