2H-Chromen-4(3H)-one.

ABSTRACT: In the title compound, C(9)H(8)O(2), a benzo-annulated heterocyclic ketone, the non-aromatic six-membered ring adopts an E(2) conformation. In the crystal, C-H?O contacts connect the mol-ecules into double sheets perpendicular to the crystallographic a axis. The centroid-centroid distance for two ?-systems is 3.7699?(6)?Å.

In the title compound, C(9)H(8)O(2), a benzo-annulated heterocyclic ketone, the non-aromatic six-membered ring adopts an E(2) conformation. In the crystal, C-H⋯O contacts connect the mol-ecules into double sheets perpendicular to the crystallographic a axis. The centroid-centroid distance for two π-systems is 3.7699 (6) Å. ...[more]

2-(4-Fluoro-phen-yl)-2H-chromen-4(3H)-one.

Project description:In the crystal structure of the title compound, C(15)H(11)FO(2), mol-ecules form inversion dimers through pairs of weak C-H⋯O hydrogen bonds. Dimers oriented in parallel, linked by C-H⋯π contacts, are arranged in columns along the b axis. The fluoro-phenyl ring and the benzene ring of the 2H-chromen-4(3H)-one unit are inclined to one another by 70.41 (16)°. They are respectively parallel in a given column or almost perpendicular [oriented at an angle of 87.8 (1)°] in neighbouring (inversely oriented) columns, forming a herringbone pattern.

4,7,8-Trimethyl-2H-chromen-2-one.

Project description:The mol-ecule of the title compound, C(12)H(12)O(2), is essentially planar, with a maximum deviation from the mean plane of all non-H atoms of 0.038 (1) Å for the methyl C atom in the 8-position. The crystal structure is characterized by anti-parallel π-π stacking along the c axis, with centroid-centroid distances as short as 3.866 (1) Å. In the crystal, C-H⋯O hydrogen bonds connect the mol-ecules across the stacks into ribbons in the a-axis direction.

3-Benzyl-2H-chromen-2-one.

Project description:The title compound, C(16)H(12)O(2), is a coumarin which was isolated from stones of the Chinese traditional medicine Clausena lansium. The pyrone ring is almost planar, with a mean deviation of 0.0135 (4) Å. The benzene ring (A) of the benzopyrone unit forms dihedral angles of 1.82 (5) and 72.86 (2)° with the pyrone ring and the substituent benzene ring, respectively. The crystal structure is stabilized by weak π-π stacking inter-actions, with a minimum centroid-centroid distance between benzene rings of 3.6761 (7) Å.

7,7'-(3,3'-Dibenzyl-3H,3'H-4,4'-bi-1,2,3-triazole-5,5'-di-yl)bis-(4-methyl-2H-chromen-2-one).

Project description:The title compound, a bis-5,5'-triazole, C(38)H(28)N(6)O(4), was observed as a side-product from the Sharpless-Meldal click reaction of the corresponding coumarin alkyne and benzyl-azide. Although the compound was present as a minor component, it crystallized in preference to the major product. The two triazole rings are almost orthogonal to each other [dihedral angle = 83.8?(1)°]. However the 4 and 4' coumarin systems are close to coplanar with their respective triazole rings [23.6?(1) and 15.1?(1)°]. Each of the benzene rings packs approximately face-to-face with the opposing coumarin ring systems, with inter-planar angles of 7.7?(1) and 25.3?(1)° and distances of 3.567?(2) and 3.929?(2)?Å between the respective centroids of the opposing rings.

6-Meth-oxy-4-methyl-2H-chromen-2-one.

Project description:The whole mol-ecule of the title coumarin derivative, C(11)H(10)O(3), is approximately planar, with a maximum deviation of 0.116?(3)?Å from the least-squares plane defined by all non-H atoms. In the crystal, adjacent mol-ecules are linked into chains along [011] via inter-molecular C-H?O hydrogen bonds.

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.

4-Bromo-methyl-6-tert-butyl-2H-chromen-2-one.

Project description:In the crystal structure of the title compound, C14H15BrO2, weak C-H⋯O inter-actions link the mol-ecules into zigzag chains extending along the c-axis direction. These chains are further assembled into (100) layers via π-π stacking inter-actions between inversion-related chromenone fragments [inter-planar distance = 3.376 (2) Å].

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.

3-Acetyl-4-hy-droxy-6,7-dimethyl-2H-chromen-2-one.

Project description:In the title coumarin derivative, C(13)H(12)O(4), the 2H-chromene ring system is essentially planar [maximum deviation = 0.047?(1)?Å]. An intra-molecular hydrogen bond is observed between the hy-droxy and the ketonic O atoms. In the crystal, pairs of inter-molecular C-H?O hydrogen bonds link inversion-related mol-ecules into dimers. Additional inter-molecular C-H?O hydrogen bonds further inter-connect these dimers into two-dimensional arrays incorporating R(2) (2)(9) ring motifs.
