4,6-Dimethoxypyrimidin-2-amine–2-(1H-indol-3-yl)acetic acid (1/1)

Abstract

In the title co-crystal C6H9N3O2·C10H9NO2, the 4,6-dimethoxypyrimidin-2-amine molecule interacts with the carboxyl group of the 2-(1H-indol-3-yl)acetic acid molecule through N—H...O and O—H...N hydrogen bonds, forming a cyclic hydrogen-bonded R22(8) motif, which is further linked by an N—H...N hydrogen bond, forming a supramolecular chain along the c axis. Neighboring chains are interlinked via C—H...O hydrogen bonds, forming a supramolecular ladder
