2-Oxo-2H-chromen-4-yl propionate.

ABSTRACT: In the title compound, C12H10O4, the atoms of the 2-oxo-2H-chromene ring system and the non-H atoms of the 4-substituent all lie on a crystallographic mirror plane. The mol-ecular structure exhibits an intra-molecular C-H?O hydrogen bond, which generates an S(6) ring. In the crystal, mol-ecules form R 3 (2)(12) trimeric units via C-H?O inter-actions which propagate into layers parallel to the ac plane. These layers are linked by weak C-H?O inter-actions along the [010] direction, generating a three-dimensional network.

Intra-molecular O-H?O hydrogen bonds stabil-ize the mol-ecular structure and the crystal structure is stabilized by weak C-H?? and ?-? inter-actions [centroid-centroid distances 3.496?(6)-3.672?(7)?Å].

2-Oxo-2H-chromen-4-yl 4-methyl-benzoate.

Project description:The asymmetric unit of the title compound, C17H12O4, consists of two independent mol-ecules. The chromen-2-one ring and the 4-methyl-benzoate side chain are inclined to one another at a dihedral angle of 64.79?(10)° in one mol-ecule and 88.3?(1)° in the other. In the crystal, mol-ecules form R 2 (2)(8) centrosymmetric dimers via C-H?O hydrogen bonds. These dimers are stacked by C-H?O hydrogen bonds, resulting in R 2 (2)(18) and R 3 (2)(16) ring motifs. ?-? stacking inter-actions between two parallel chromen-2-one rings, with centroid-centroid distances of 3.743?(1) and 3.771?(1)?Å, are also present.

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.

2-Oxo-2H-chromen-4-yl 4-meth-oxy-benzoate.

Project description:In the title mol-ecule, C17H12O5, the chromen-2-one ring and the 4-meth-oxy-benzoate side chain are inclined to one another at a dihedral angle of 69.82?(9)°. The crystal structure features parallel sheets of centrosymmetric R2(2)(6) dimers joined by a C(7) chain, resulting in centrosymetric tetra-mers of hydrogen-bonded mol-ecules with graph-set motif R4(4)(40). These centrosymetric tetra-mers are connected by a pair of hydrogen bonds described by an R2(2)(8) ring motif and a C(7) chain via C-H?O inter-actions. In the structure, there are also ?-? stacking inter-actions between chromene benzene and the six-membered heterocyclic rings [centroid-centroid distance = 3.691?(2)?Å] and weak C=O?? inter-actions [O?(ring centroid) distance = 3.357?(3)?Å].

N-(2-Oxo-2H-chromen-3-yl)cyclo-hexane-carboxamide.

Project description:In the title compound, C16H17NO3, the coumarin moiety is essentially planar [maximum deviation from the mean plane formed by the C and O atoms of the coumarin = 0.0183?(12)?Å] and that the cyclo-hexane ring adopts the usual chair conformation. The dihedral angle between the mean plane of the coumarin residue and the plane of the amide residue (defined as the N, C and O atoms) is 18.9?(2)°. There are two intra-molecular hydrogen bonds involving the amide group. In one, the N atom acts as donor to the ketonic O atom and in the other, the amide O atom acts as acceptor of a C-H group of the coumarin. In the crystal, mol-ecules are linked into inversion dimers by pairs of N-H?O contacts and these dimers are linked into pairs by weak C-H?O hydrogen bonds. The combination of these inter-actions creates a chain of rings which runs parallel to [2-10]. C-H?? and ?-? [centroid-centroid distance = 3.8654?(10)?Å] inter-actions are also observed.

2-Oxo-2H-chromen-4-yl 4-tert-butyl-benzoate.

Project description:In the title mol-ecule, C(20)H(18)O(4), the three methyl groups of the tert-butyl substituent show rotational disorder. Each methyl group is split over three positions, with refined site-occupation factors of 0.711?(4), 0.146?(3) and 0.144?(4). The benzene ring of the benzoate group is oriented at a dihedral angle of 60.70?(7)° with respect to the planar chromene ring [maximum deviation = 0.046?(2)?Å]. The crystal structure features centrosymmetric R(2) (2)(8) dimers formed via C-H?O inter-actions, and these dimeric aggregates are connected by C-H?? inter-actions.

Ethyl 2-[(2-oxo-2H-chromen-7-yl)-oxy]acetate.

Project description:In the title compound, C13H12O5, the mean plane of the 2H-chromene ring system (r.m.s deviation = 0.026?Å) forms a dihedral angle of 81.71?(6)° with the mean plane of ethyl 2-hy-droxy-acetate moiety (r.m.s deviation = 0.034?Å). In the crystal, C-H?O hydrogen bonds result in the formation of zigzag layers parallel to the bc plane.

2-Oxo-2H-chromen-7-yl 4-tert-butyl-benzoate.

Project description:In the title compound, C20H18O4, the benzoate ring is oriented at an acute angle of 33.10 (12)° with respect to the planar (r.m.s deviation = 0.016 Å) coumarin ring system. An intra-molecular C-H⋯O hydrogen bond closes an S(6) ring motif. In the crystal, C-H⋯O contacts generate infinite C(6) chains along the b-axis direction. Also present are π-π stacking inter-actions between neighbouring pyrone and benzene rings [centroid-centroid distance = 3.7034 (18) Å] and C=O⋯π inter-actions [O⋯centroid = 3.760 (3) Å]. The data obtained from quantum chemical calculations performed on the title compound are in good agreement with the observed structure, although the calculated C-O-C-C torsion angle between the coumarin ring system and the benzoate ring (129.1°) is somewhat lower than the observed value [141.3 (3)°]. Hirshfeld surface analysis has been used to confirm and qu-antify the supra-molecular inter-actions.

8-Acetyl-4-methyl-2-oxo-2H-chromen-7-yl acetate.

Project description:In the title compound, C(14)H(12)O(5), the benzopyran-2-one ring system is approximately planar [maximum deviation = 0.018?(1)?Å]; the mean plane is oriented at dihedral angles of 52.26?(11) and 72.92?(7)°, respectively, to the acetyl and acet-oxy groups. In the crystal, ?-? stacking is observed between parallel benzene rings of adjacent mol-ecules, the centroid-centroid distance being 3.6774?(17)?Å. Inter-molecular weak C-H?O hydrogen bonding, and C=O?C=O [O?C = 3.058?(3)?Å] and C=O?? [O?centroid = 3.328?(2)?Å] inter-actions occur in the crystal structure.
