2-Amino-4-(4-meth­oxy­phen­yl)-5-oxo-4H,5H-pyrano[3,2-c]chromene-3-carbo­nitrile acetic acid monosolvate

In the title co-crystal, C(20)H(14)N(2)O(4)·C(2)H(4)O(2), the expected proton transfer from acetic acid to amine has not occurred. In the crystal, the chromene mol­ecules are linked by N—H⋯O and N—H⋯N hydrogen bonds to generate [100] columns. The acetic acid mol­ecules form inversion dimers linked b...

Sumario:In the title co-crystal, C(20)H(14)N(2)O(4)·C(2)H(4)O(2), the expected proton transfer from acetic acid to amine has not occurred. In the crystal, the chromene mol­ecules are linked by N—H⋯O and N—H⋯N hydrogen bonds to generate [100] columns. The acetic acid mol­ecules form inversion dimers linked by pairwise O—H⋯O hydrogen bonds and occupy voids between the columns. [Image: see text]
