5-Hydr-oxy-7-meth-oxy-4H-chromen-4-one.

ABSTRACT: The mol-ecular conformation of the title compound, C(10)H(8)O(4), isolated from Laretia acualis, is stabilized by a strong intra-molecular hydrogen bond between the hydroxyl and carbonyl groups. The crystal packing shows ?-? stacking inter-actions. The chromene (4H-1-benzopyran-4-one) unit is essentially planar.

The mol-ecular conformation of the title compound, C(10)H(8)O(4), isolated from Laretia acualis, is stabilized by a strong intra-molecular hydrogen bond between the hydroxyl and carbonyl groups. The crystal packing shows π-π stacking inter-actions. The chromene (4H-1-benzopyran-4-one) unit is essentially planar. ...[more]

8-Hydr-oxy-5,6,7-trimeth-oxy-2-phenyl-4H-chromen-4-one.

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.

3-Hy-droxy-2-(4-meth-oxy-phen-yl)-4H-chromen-4-one.

Project description:In the title compound, C(16)H(12)O(4), the benzene ring is twisted at an angle of 12.3 (1)° relative to the 4H-chromene skeleton, and an intramolecular O-H⋯O hydrogen bond occurs. The meth-oxy group is almost coplanar with the benzene ring [1.5 (1)°]. In the crystal, inversely oriented mol-ecules are arranged in double (A, A') columns, along the b axis, and are linked by a network of inter-molecular O-H⋯O hydrogen bonds (between A and A') and C-H⋯π contacts (within A or A'). The 4H-chromene cores are parallel within A or A', but make a dihedral angle of 88.6 (1)° between A and A'.

2-(4-Hy-droxy-phen-yl)-3-meth-oxy-4H-chromen-4-one.

Project description:In the title compound, C16H12O4, the substituent benzene ring and meth-oxy group are twisted relative to the 4H-chromene skeleton by 24.1 (1) and 61.3 (1)°, respectively. In the crystal, mol-ecules are connected by classical O-H⋯O and weak C-H⋯O hydrogen bonds, forming chains parallel to [201]. The 4H-chromene ring systems of adjacent mol-ecules are either parallel or inclined at an angle of 28.9 (1)°.

Project description:In the title compound, C(18)H(16)O(6), the dimethoxy-phenyl ring is rotated by 61.8?(1)° from the plane of the benzopyran system. The mol-ecule is stabilized by an intra-molecular O-H?O hydrogen bond.

Project description: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 with R (2) 2(10) loops and C-H?O inter-actions connect the dimers into [010] chains.

Project description:The title mol-ecule, C19H12S2O2, lies on a twofold rotation axis. The thio-chromonone unit is essentially planar, with a maximum deviation of 0.0491?(14)?Å.

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.

5-Hydr-oxy-2-methyl-4H-pyran-4-one.

Project description:The title compound, C(6)H(6)O(3), is a member of the pyrone family. The mol-ecules are planar (r.m.s. deviation of the asymmetric unit is 0.0248?Å, whereas that of the dimer is 0.0360?Å) and they are dimerized due to inter-molecular O-H?O hydrogen bonds. The dimers are connected to each other through hydrogen bonds involving the CH(3) group and the hydr-oxy O atom. There are ?-? inter-actions between the centroids of the pyrone rings at a distance of 3.8552?(13)?Å. A C-H?? inter-action also exists between the carbonyl group and the centroid CgA of the pyrone ring, with O?CgA = 3.65?(1)?Å and C?CgA = 4.363?(2)?Å.

Crystal structure of 2-(3,4-di-meth-oxy-phen-yl)-3-hy-droxy-4H-chromen-4-one.

Project description:In the title compound, C17H14O5, the dimeth-oxy-substituted benzene ring is twisted relative to the 4H-chromenon skeleton (r.m.s. deviation = 0.015 Å) by 5.2 (4)°. The C atoms of the meth-oxy groups lie close to the plane of their attached benzene ring [deviations = 0.036 (3) and 0.290 (3)Å for the meta and para substituents, respectively]. An intra-molecular O-H⋯O hydrogen bond closes an S(5) ring. In the cystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R 2 (2)(10) loops and C-H⋯O inter-actions connect the dimers into [010] chains.
