title: 4,6-Dimeth-oxy-pyrimidin-2-amine-2-(1H-indol-3-yl)acetic acid (1/1).
abstract: In the title co-crystal C(6)H(9)N(3)O(2)·C(10)H(9)NO(2), the 4,6-dimeth-oxy-pyrimidin-2-amine mol-ecule inter-acts with the carboxyl group of the 2-(1H-indol-3-yl)acetic acid mol-ecule through N-H⋯O and O-H⋯N hydrogen bonds, forming a cyclic hydrogen-bonded R(2) (2)(8) motif, which is further linked by an N-H⋯N hydrogen bond, forming a supra-molecular chain along the c axis. Neighboring chains are inter-linked via C-H⋯O hydrogen bonds, forming a supra-molecular ladder.
