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.
在标题共晶体C(6)H(9)N(3)O(2)·C(10)H(9)NO(2)中,4,6-二甲氧基嘧啶-2-胺分子通过N-H⋯O和O-H⋯N氢键与2-(1H-吲哚-3-基)乙酸分子的羧基相互作用,形成环状氢键R(2) (2)(8)基序,该基序通过N-H⋯N氢键进一步连接,沿c轴形成超分子链。相邻链通过C-H⋯O氢键相互连接,形成超分子梯子。
