3,3'-[(4-Nitro-phen-yl)methyl-ene]bis-(4-hy-droxy-2H-chromen-2-one).

ABSTRACT: The molecular conformation of the title compound, C(25)H(15)NO(8), is stabilized by strong intramolecular O-H⋯O hydrogen bonds, resulting in the formation of S(1) (1)(7) ring motifs. In the crystal, π-π stacking inter-actions are observed between adjacent nitrobenzene and pyranone rings with a centroid-centroid distance of 3.513 (12) Å. The dihedral angles between the nitrobenzene ring and the coumarin ring systems are 65.61 (8) and 66.11 (8)° while the coumarin ring systems are inclined at 65.69 (8)°.

2,2'-{[2-(2-Hy-droxy-phen-yl)-4-methyl-imidazolidine-1,3-di-yl]bis-(methyl-ene)}diphenol.

Project description:The asymmetric unit in the title compound, C24H26N2O3, comprises two independent mol-ecules (A and B). In molecule A, the central 2-hydroxyphenyl ring is inclined to the mean plane of the major component of the imidazolidine ring by 84.52 (14)°, and by 68.08 (9) and 47.48 (9)° to the outer phenol rings. The later are inclined to one another by 66.76 (9)° and by 78.12 (14) and 80.20 (14)° to the imidazoline ring mean plane. In molecule B, the central 2-hydroxyphenyl ring is inclined to the mean plane of the imidazolidine ring by 73.64 (10)°, and by 75.60 (8) and 38.32 (9)° to the outer phenol rings. The later are inclined to one another by 69.47 (9)° and by 82.60 (10) and 64.26 (10)° to the imidazolidine ring mean plane. In each of the independent mol-ecules, two intra-molecular O-H⋯N hydrogen bond form S(6) ring motifs. In disordered mol-ecule A, the O-H groups of the 2-hy-droxy-benzyl groups are also involved in intra-molecular O-H⋯O hydrogen bonds, with the O atom of the hy-droxy-phenyl group acting as the acceptor. In the crystal, A molecules are linked by pairs of O-H⋯O hydrogen bonds forming inversion dimers. These dimers are linked to the B molecules via O-H⋯O hydrogen bonds forming double-layered slabs lying parallel to the bc plane.

4-Hy-droxy-3-[(4-hy-droxy-2-oxo-2H-3-chromen-yl)(3-thien-yl)meth-yl]-2H-chromen-2-one.

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.

Project description:In the title compound, C(18)H(14)O(4)·C(2)H(6)O, the coumarin ring system is approximately planar with a maximum deviation of 0.037 (3) Å and is nearly perpendicular to the benzene ring, making a dihedral angle of 86.55 (9)°. In the crystal, mol-ecules are linked by classical O-H⋯O hydrogen bonds and weak C-H⋯O inter-actions.

Project description:In the title compound, C(13)H(9)NO(6), the coumarin system has the benzene ring aligned at 0.61 (18)° with respect to the pyrone ring. An intra-molecular O-H⋯O hydrogen bond stabilizes the mol-ecular conformation and a C-H⋯O contact also occurs. In the crystal, weak C-H⋯O inter-actions link the mol-ecules, forming inversion dimers.

1,1'-[(5-Hy-droxy-methyl-1,3-phenyl-ene)bis-(methyl-ene)]dipyridin-4(1H)-one monohydrate.

Project description:The asymmetric unit of the title compound, C(19)H(18)N(2)O(3), comprises a whole organic dipyridinone mol-ecule plus a water mol-ecule of crystallization. The planes of the pyridinone rings are approximately perpendicular with the plane of the central aromatic ring [dihedral angles = 80.68 (8) and 83.65 (8)°]. The C-O bond of the hy-droxy group subtends an angle of 31.71 (10)° with the plane through the central aromatic ring. The crystal packing is mediated by the presence of several O-H⋯O hydrogen-bonding inter-actions and while the water mol-ecules form a C(2) (1)(4) chain parallel to the c axis of the unit cell, the pendant hy-droxy groups are engaged in O-H⋯O=C hydrogen bonds described by a C(1) (1)(12) graph-set motif which runs parallel to the a axis.

A void of 33.0 (7) Å(3) is observed in the crystal structure. The solvent ethanol molecule acts as a donor, forming an O-H⋯O hydrogen bond, reinforcing the framework structure.

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

Project description: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.
