2-(Furan-2-yl)-3-hy-droxy-4H-chromen-4-one.

ABSTRACT: In the crystal structure of the title compound, C(13)H(8)O(4), the inversely oriented mol-ecules form inversion dimers through pairs of O-H?O hydrogen-bonding inter-actions. An intramolecular O-H?O hydrogen bond occurs. In the packing of the mol-ecules, the nearly planar 2-(furan-2-yl)-4H-chromene units [dihedral angle between the chromene and furan rings = 3.8?(1)°] are either parallel or inclined at an angle of 80.7?(1)°.

In the crystal structure of the title compound, C(13)H(8)O(4), the inversely oriented mol-ecules form inversion dimers through pairs of O-H⋯O hydrogen-bonding inter-actions. An intramolecular O-H⋯O hydrogen bond occurs. In the packing of the mol-ecules, the nearly planar 2-(furan-2-yl)-4H-chromene units [dihedral angle between the chromene and furan rings = 3.8 (1)°] are either parallel or inclined at an angle of 80.7 (1)°. ...[more]

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.

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, 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 hydrogen bonds stabil-ize the mol-ecular structure and the crystal structure is stabilized by weak C-H?? and ?-? inter-actions [centroid-centroid distances 3.496?(6)-3.672?(7)?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.

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.

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.
