ABSTRACT: In the title compound, C(36)H(28)O(5), the terminal benzene rings are twisted at dihedral angles of 6.75?(12), 70.86?(14) and 82.02?(12)° with the respect to the central plana r[maximum deviation = 0.070?(3)?Å] chromen-4-one ring system. In the crystal structure, ?-? stacking is observed between parallel benzene rings of adjacent mol-ecules [centroid-centroid distance = 3.7459?(16)?Å].

[3,5-Bis(benz-yloxy)phen-yl]methanol.

Project description:In the title compound, C(21)H(20)O(3), the two terminal phenyl rings are each approximately perpendicular to the central benzene ring, making dihedral angles of 84.40?(16) and 75.12?(15)°. The H atom of the hydr-oxy group is disordered over two positions with equal occupancies. The mol-ecules are linked by O-H?O hydrogen bonds, forming a chain along the a axis.

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.

Crystal structure of 3-[4-(benz-yloxy)phen-yl]-2,3-di-hydro-1H-benzo[f]chromen-1-one.

Project description:In the title compound, C26H20O3, the pyran ring has a distorted half-chair conformation and its mean plane is inclined to the naphthalene ring system, to which it is fused, by 10.79?(9)°. The dihedral angles between the napthalene unit and the benzene and phenyl rings are 54.39?(9) and 52.65?(12)°, respectively, while the benzene and phenyl rings are inclined to one another by 74.80?(14)°. There is a short C-H?O contact in the chromen-1-one unit. In the crystal, mol-ecules are linked by two pairs of C-H?O hydrogen bonds, forming inversion dimers described by graph set motifs R 2 (2)(8) and R 2 (2)(10), giving rise to chains running parallel to (101). The chains are linked via C-H?? inter-actions, forming sheets lying parallel to (010).

Project description:The title compound, C(18)H(16)O(7)·H(2)O, is a flavonoid isolated from Dodonaea viscosa-.

The crystal structure is further stabilized by ?-? stacking inter-actions [centroid-centroid distance between benzene rings = 3.564?(3)?Å].
