چکیده
In the crystal structure of the title compound, C(13)H(8)O(4), the inversely oriented mol-ecules form inversion dimers through pairs of O-H⋯O hydrogen-bonding inter-actions. An intramolecular O-H⋯O hydrogen bond occurs. In the packing of the mol-ecules, the nearly planar 2-(furan-2-yl)-4H-chromene units [dihedral angle between the chromene and furan rings = 3.8 (1)°] are either parallel or inclined at an angle of 80.7 (1)°.

The title mol-ecule, C(18)H(14)N(2)O(5)S·C(3)H(7)NO, comprises of a carboxamide group bonded to a furan ring and a distorted envelope-shaped 4-oxothia-zolidin-3-yl group which is connected to a substituted 6-methyl-4-oxo-4H-chromen-3-yl group. Extensive strong N-H⋯O and weak C-H⋯O inter-molecular hydrogen-bonding inter-actions occur between dimethyl-formamide (DMF), the crystallizing solvent, a...

In the title compound, C22H18O6, the dimeth-oxy-substituted naphthalene ring system is twisted relative to the 4H-chromenon skeleton by 88.96 (3)°. The two meth-oxy substituents are tilted from the naphthalene ring system by 1.4 (4) and 113.0 (2)°, respectively. An intra-molecular O-H⋯O hydrogen bond closes an S(5) ring motif. In the crystal, pairs of O-H⋯O hydrogen bonds form inversion dimers ...
