Crystal structures of two 4H-chromene derivatives: 2-amino-3-cyano-4-(3,4-dichlorophenyl)-7-hydroxy-4H-benzo[1,2-b]pyran 1,4-dioxane monosolvate and 2-amino-3-cyano-4-(2,6-dichlorophenyl)-7-hydroxy-4H-benzo[1,2-b]pyran
In the title compounds, C(16)H(9)Cl(2)N(2)O(2)·C(4)H(8)O(2) and C(16)H(9)Cl(2)N(2)O(2), the bicyclic 4H-chromene cores are nearly planar with maximum deviations of 0.081 (2) and 0.087 (2) Å. In both structures, the chromene derivative molecules are linked into centrosymmetric dimers by pairs of N—H...
