Crystal structure of 3-bromo-acetyl-6-chloro-2H-1-benzo-pyran-2-one.

ABSTRACT: In the title compound, C11H6BrClO3, the benzo-pyran ring system is essentially planar, with a maximum deviation of 0.036?(2)?Å for the O atom. The Cl and Br atoms are displaced by -0.0526?(8) and 0.6698?(3)?Å, respectively, from the mean plane of this ring system. In the crystal, two pairs of weak C-H?O hydrogen bonds to the same acceptor O atom link mol-ecules into inversion dimers.

In the title compound, C11H6BrClO3, the benzo-pyran ring system is essentially planar, with a maximum deviation of 0.036 (2) Å for the O atom. The Cl and Br atoms are displaced by -0.0526 (8) and 0.6698 (3) Å, respectively, from the mean plane of this ring system. In the crystal, two pairs of weak C-H⋯O hydrogen bonds to the same acceptor O atom link mol-ecules into inversion dimers. ...[more]

Project description:The title compound, C11H6Br2O4, is a new coumarin derivative obtained from the reaction of 3-acetyl-4-hy-droxy-2H-chromen-2-one with bromine in acetic acid.

Crystal structure of a new polymorph of 3-acetyl-8-meth-oxy-2H-chromen-2-one.

Project description:A new polymorphic form of the title compound, C12H10O4, is described in the ortho-rhom-bic space group Pbca and Z = 8, as compared to polymorph I, which crystallizes in the monoclinic space group C2/c and Z = 8 [Li et al. (2012). Chin. J. Struct. Chem. 31, 1003-1007.]. In polymorph II, the coumarin ring system is almost planar (r.m.s. deviation = 0.00129?Å). In the crystal, mol-ecules are connected by Csp 3-H?O and Car-H?O hydrogen bonds, forming mol-ecular sheets linked into zigzag shaped layers along the b-axis direction. The three-dimensional lattice is assembled through stacking of the zigzag layers by ?-? inter-actions with a centroid-to-centroid distance of 3.600?(9)?Å and anti-parallel C=O?C=O inter-actions with a distance of 3.1986?(17)?Å, which give rise to a helical supra-molecular architecture.

Crystal structure of 4-(4-chloro-phen-yl)-6-(morpholin-4-yl)pyridazin-3(2H)-one.

Project description:In the title compound, C14H14ClN3O2, the morpholine ring adopts a chair conformation, with the exocyclic N-C bond in an equatorial orientation. The 1,6-di-hydro-pyridazine ring is essentially planar, with a maximum deviation of 0.014 (1) Å, and forms a dihedral angle of 40.16 (7)° with the plane of the benzene ring. In the crystal, pairs of centrosymmetrically related mol-ecules are linked into dimers via N-H⋯O hydrogen bonds, forming R 2 (2)(8) ring motifs. The dimers are connected via C-H⋯O and C-H⋯Cl hydrogen bonds, forming a three-dimensional network. Aromatic π-π stacking inter-actions [centroid-centroid distance = 3.6665 (9) Å] are also observed. Semi-empirical mol-ecular orbital calculations were carried out using the AM1 method. The calculated dihedral angles between the pyridizine and benzene rings and between the pyridizine and morpholine (all atoms) rings are 34.49 and 76.96°, respectively·The corresponding values obtained from the X-ray structure determination are 40.16 (7) and 12.97 (9)°, respectively. The morpholine ring of the title compound in the calculated gas-phase seems to have a quite different orientation compared to that indicated by the X-ray structure determination.

Crystal structure of 3-bromo-2-hy-droxy-benzo-nitrile.

Project description:The crystal structure of the title compound, C7H4BrNO, has been determined, revealing a partial mol-ecular packing disorder such that a 180° rotation of the mol-ecule about the phenol C-O bond results in disorder of the bromine and nitrile groups. The disorder has been parameterized as a disorder of only the bromine and nitrile substituents on a unique phenol ring. An intra-molecular O-H⋯Br contact occurs. In the crystal, O-H⋯Br/O-H⋯Nnitrile hydrogen bonding is present between the disordered bromine and nitrile substituents and the phenol group, forming a spiral chain about a twofold screw axis extending parallel to the b-axis direction. Within this spiral chain, the mol-ecules also inter-act, forming offset face-to-face π-stacking inter-actions with plane-to-centroid distance of 3.487 (1) Å.

C-H?O interactions also occur.

Crystal structure of di-bromo-meth-oxy-seselin (DBMS), a photobiologically active pyran-ocoumarin.

Project description:The title compound, C15H14Br2O4 [systematic name: rac-(9S,10R)-3,9-dibromo-10-methoxy-8,8-dimethyl-9,10-dihydropyrano[2,3-h]chromen-2(8H)-one], is a pyran-ocoumarin derivative formed by the bromination of seselin, which is a naturally occurring angular pyran-ocoumarin isolated from the Indian herb Trachyspermum stictocarpum. In the mol-ecule, the benzo-pyran ring system is essentially planar, with a maximum deviation of 0.044 (2) Å for the O atom. The di-hydro-pyran ring is in a half-chair conformation and the four essentially planar atoms of this ring form a dihedral angle of 4.6 (2)° with the benzo-pyran ring system. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming chains propagating along [010]. In addition, π-π stacking inter-actions, with centroid-centroid distances of 3.902 (2) and 3.908 (2) Å, link the hydrogen-bonded chains into layers parallel to (001).
