(Z)-3-(1-Hy-droxy-3-oxobut-1-en-yl)-6-nitro-2H-chromen-2-one.

ABSTRACT: In the title compound, C(13)H(9)NO(6), the coumarin system has the benzene ring aligned at 0.61 (18)° with respect to the pyrone ring. An intra-molecular O-H⋯O hydrogen bond stabilizes the mol-ecular conformation and a C-H⋯O contact also occurs. In the crystal, weak C-H⋯O inter-actions link the mol-ecules, forming inversion dimers.

Project description: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) graph-set motif. In the crystal, the mol-ecules are linked by inter-molecular C-H⋯O inter-actions, forming chains along the b axis. The structure is further stabilized by π-π inter-actions with centroid-centroid distances of 3.594 (2) and 3.608 (5) Å.

3-[(E)-3-(2,4-Dichloro-phen-yl)prop-2-en-oyl]-4-hy-droxy-2H-chromen-2-one.

Project description:In the title compound, C(18)H(10)Cl(2)O(4), the chromen-2-one ring system is almost planar [maximum deviation = 0.028 (1) Å] and is inclined at an angle of 16.35 (4)° with respect to the benzene ring. The C=C bond has an E configuration. The mol-ecular conformation is stabilized by an almost symmetric intra-molecular O⋯H⋯O hydrogen bond and a C-H⋯O inter-action, both of which form S(6) ring motifs. In the crystal structure, mol-ecules are linked into sheets lying parallel to (100) via inter-molecular C-H⋯O hydrogen bonds. The crystal packing is further consolidated by π-π stacking inter-actions [centroid-to-centroid separation = 3.6615 (6) Å].

Project description:The title compound, C(23)H(24)O(6), crystallizes with two independent mol-ecules (A and B) in the asymmetric unit.

7-Hy-droxy-6-meth-oxy-2H-chromen-2-one.

Project description:The title compound, C(10)H(8)O(4), is one of the coumarins existing in Morinda citrifolia L (Noni). The chromenone ring system is approximately planar with a maximum deviation of 0.0208 (14) Å.

In the crystal packing, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into chains. These are further connected by C-H⋯O hydrogen bonds.
