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

ABSTRACT: 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.

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.

(E)-3,4,5-Trimeth-oxy-N'-[(4-oxo-4H-chromen-3-yl)methyl-idene]benzo-hydrazide.

Project description:In the title chromone-tethered benzohydrazide derivative, C20H18N2O6, the atoms of the E-3-(hydrazonometh-yl)-4H-chromen-4-one segment are essentially coplanar, the largest deviation being 0.065 (6) Å. The dihedral angle between this segment and the benzene ring of the tri-meth-oxy-benzene unit is 40.18 (10) Å. In the crystal, the mol-ecule is linked to its inverse-symmetry equivalent by pairs of N-H⋯O hydrogen bonds and C-H⋯π inter-actions. The -CH=N-NH- segment is stacked on the benzene ring of the chromone unit of a translation-related equivalent mol-ecule [centroid-centroid distance = 3.413 (6) Å].

Adjacent networks interact by ?-? inter-actions between the pyran ring and its methoxy-phenyl substituent [centroid-centroid distance = 3.5267?(8)?Å].
