4-Hydroxy-3-[(4-hydroxy-6,7-dimethyl-2-oxo-2H-chromen-3-yl)(4-oxo-4H-chromen-3-yl)methyl]-6,7-dimethyl-2H-chromen-2-one
In the title compound, C(32)H(24)O(8), the mol-ecular structure is disordered over two positions with refined site occupancies of 0.8746 (10) and 0.1254 (10). The mean plane of the three chromeno rings make dihedral angles with each other of 65.12 (4), 62.91 (4) and 59.70 (4)° in the major occupancy component and 59.1 (3), 66.1 (3) and 58.8 (3)° in the minor component. Intra-molecular O-H⋯O hyd...

In the mol-ecule of the title compound, C(17)H(10)BrNO(5), the indoline system and the attached coumarin ring are each essentially planar with maximum deviations of 0.074 (2) and 0.062 (2) Å, respectively. The dihedral angle between them is 85.09 (3)°. In the crystal, all heteroatoms (except for the coumarin oxo O atoms) are involved in intra- and inter-molecular hydrogen bonds. An intra-molecu...
متن کامل4-Hydroxy-3-[(4-hydroxy-2-oxo-2H-3-chromenyl)(3-thienyl)methyl]-2H-chromen-2-one
The whole mol-ecule of the title compound, C(23)H(14)O(6)S, is disordered over two sets of sites with refined occupancies of 0.8733 (12):0.1267 (12). The dihedral angle between the mean planes through the chromene ring systems is 56.31 (5) and 55.2 (3)° for the major and minor components, respectively. In both components, a pair of intra-molecular O-H⋯O inter-actions generate rings of S(8) grap...
متن کامل2-Oxo-2H-chromen-4-yl propionate
In the title compound, C12H10O4, the atoms of the 2-oxo-2H-chromene ring system and the non-H atoms of the 4-substituent all lie on a crystallographic mirror plane. The mol-ecular structure exhibits an intra-molecular C-H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, mol-ecules form R 3 (2)(12) trimeric units via C-H⋯O inter-actions which propagate into layers parallel to the a...
متن کامل3-Acetyl-4-hydroxy-6,7-dimethyl-2H-chromen-2-one
In the title coumarin derivative, C(13)H(12)O(4), the 2H-chromene ring system is essentially planar [maximum deviation = 0.047 (1) Å]. An intra-molecular hydrogen bond is observed between the hy-droxy and the ketonic O atoms. In the crystal, pairs of inter-molecular C-H⋯O hydrogen bonds link inversion-related mol-ecules into dimers. Additional inter-molecular C-H⋯O hydrogen bonds further inter-...
