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

ABSTRACT: 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. The meth-oxy group does not deviate from this plane [C-O-C-C torsion angle = -1.5?(3)°], indicating that the whole mol-ecule is almost planar. 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.

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. The meth-oxy group does not deviate from this plane [C-O-C-C torsion angle = -1.5 (3)°], indicating that the whole mol-ecule is almost planar. 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. ...[more]

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 ?-? inter-actions with centroid-centroid distances of 3.594?(2) and 3.608?(5)?Å.

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'.

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].

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.
