5,7-Dimeth-oxy-2-phenyl-4H-chromen-4-one.

ABSTRACT: The asymmetric unit of the title compound, C(17)H(14)O(4), contains two independent mol-ecules which differ in the relative orientations of the phenyl rings with repect to the essentially planar [maximum deviations of 0.029?(2) and 0.050?(2)?Å in the two mol-ecules] chromene fused-ring system, forming dihedral angles of 10.3?(5) and 30.86?(5)° in the two mol-ecules. The crystal structure is stabilized by weak C-H?O and C--H?? inter-actions, and ?-? stacking inter-actions.

The asymmetric unit of the title compound, C(17)H(14)O(4), contains two independent mol-ecules which differ in the relative orientations of the phenyl rings with repect to the essentially planar [maximum deviations of 0.029 (2) and 0.050 (2) Å in the two mol-ecules] chromene fused-ring system, forming dihedral angles of 10.3 (5) and 30.86 (5)° in the two mol-ecules. The crystal structure is stabilized by weak C-H⋯O and C--H⋯π inter-actions, and π-π stacking inter-actions. ...[more]

5,7-Dihy-droxy-2-(3-hy-droxy-4,5-dimeth-oxy-phen-yl)-6-meth-oxy-4H-chromen-4-one.

Project description:The title compound, C18H16O8, was isolated from the plant Artemisia baldshuanica Krasch et Zarp. The mol-ecule is approximately planar, with the exception of the terminal methyl groups, the C atoms of which devitate from their attached ring planes by 1.243 (5) and 1.168 (5) Å. The dihedral angle between the substituted benzopyran and benzene rings is 5.8 (1)°; this near planarity could be due to conjugation or a packing effect. Intra-molecular O-H⋯O and C-H⋯O hydrogen bonds occur. In the crystal, mol-ecules are connected by O-H⋯O hydrogen bonds involving the hy-droxy and carbonyl groups, forming hydrogen-bonded chains along [001] and [1-10]. The chains are linked by C-H⋯O inter-actions.

8-Iodo-5,7-dimeth-oxy-4-methyl-2H-chromen-2-one.

Project description:In the title compound, C(12)H(11)IO(4), the C and O atoms of both meth-oxy groups lie very close to the mean plane of the six C atoms of the benzene ring. The O and C atoms of the group lying closest to the I atom are 0.012 (3) and 0.022 (4) Å, respectively, out of the mean plane. For the other meth-oxy group, the corresponding distances are 0.020 (3) and 0.078 (4) Å. In the crystal, there are only very weak inter-molecular C-H⋯O hydrogen bonds and O⋯I contacts [3.080 (2) Å]. The mol-ecules are approximately parallel to (100), forming a layered structure.

5,7-Dihy-droxy-3,6-dimeth-oxy-2-(4-meth-oxy-phen-yl)-4H-chromen-4-one monohydrate.

Project description:The title compound, C(18)H(16)O(7)·H(2)O, is a flavonoid isolated from Dodonaea viscosa-. The benzopyran ring system of the flavonoid is essentially planar [maximum deviation = 0.025?(2)?Å] and inclined at 5.83?(2)° to the attached benzene ring. The water of hydration is involved in extensive hydrogen bonding, assembling the mol-ecules into a supra-molecular network via classical inter-molecular O-H?O hydrogen bonding. The crystal structure is further stabilized by ?-? stacking inter-actions [centroid-centroid distance between benzene rings = 3.564?(3)?Å].

Project description:In the title compound, C(18)H(16)O(6), the benzopyran group is essentially planar, with the O atoms of the substituent groups lying close to its mean plane. The mol-ecular conformation is governed by intra-molecular inter-actions. The crystal packing is mainly determined by one classical inter-molecular hydrogen bond which gives rise to the formation of an infinite chain along the a axis.

5,7-Dimeth-oxy-2-(4-methoxy-phen-yl)-4H-1-benzopyran-4-one methanol solvate monohydrate.

Project description:In the title compound (alternatively called 4',5,7-trimethoxy-flavone methanol solvate hydrate), C(18)H(16)O(5)·CH(3)OH·H(2)O, the flavone mol-ecule is almost planar, the inter-planar angle between the planes of the benzopyran-4-one group and the attached benzene ring being 4.69?(9)°. In the crystal, the flavone mol-ecule makes inter-molecular C-H?O hydrogen bonds to adjacent inversion-related flavone mol-ecules, generating R(2) (2)(8) and R(2) (2)(14) rings and an infinite ribbon. The inversion-related ribbons are stabilized through the inter-stitial water and methanol mol-ecules via inter-molecular O-H?O hydrogen bonds, generating R(4) (2)(8) and R(2) (1)(6) rings and C(2) (2)(4) chains, and are further sustained by ?-? inter-actions with an inter-planar spacing of 3.365?(2)Å.

In addition, the stacked mol-ecules exhibit inter- and intra-molecular O-H⋯O hydrogen bonds, including the uncoordinated water mol-ecules.
