description |
There are two independent molecules in the asymmetric unit of the title compound, C19H16N2O5S, in which the thiazole rings make dihedral angles of 80.89 (11) and 84.81 (11)° with the pyrano[3,2-c]chromene ring systems. An intramolecular N—H...O hydrogen bond involving the amino group occurs in each independent molecule. In the crystal, the amino groups are involved in N—H...O and N—H...N hydrogen bonds. |
