3-(2-Chloro-3-hy-droxy-4-meth-oxy-phen-yl)-1-(4,5-dimeth-oxy-2-methyl-phen-yl)prop-2-en-1-one.

ABSTRACT: The title compound, C(19)H(19)ClO(5), is a chloro derivative of a biologically significant chalcone family. The mean plane of the two substituted benzene rings are twisted by 55.33?(8)° with respect to each other. An intra-molecular C-H?Cl hydrogen bond generates an S(5) graph-set motif. In the crystal, a bifurcated O-H?(O,O) hydrogen bond leads to an R(1) (2)(5) graph-set motif and to the formation of zigzag chains propagating along the c-axis direction. A weak ?-? inter-action involving the methyl-phenyl rings [centroid-centroid distance = 3.8185?(10)?Å] and C-H?? inter-actions also occur.

Project description:The planar -CH=CHC(=O)- fragment (r.m.s. deviation = 0.074?Å) in the title compound, C(18)H(18)O(5), connects the planar hy-droxy-dimeth-oxy-phenyl (r.m.s. deviation = 0.039?Å) and meth-oxy-lphenyl (r.m.s. deviation = 0.021?Å) parts. The central fragment forms a dihedral angle of 13.7?(1)° with the hy-droxy-dimeth-oxy-phenyl part and 32.0?(1)° with the meth-oxy-phenyl part. The hy-droxy group forms an intra-molecular hydrogen bond to the carbonyl O atom.

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.

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].
