ABSTRACT: In the title compound, C(35)H(28)O(6)·C(7)H(8), the dihedral angle between the mean planes through the naphthalene ring systems of the dibenzo[a,g]fluorene moiety is 22.44?(3)°. The aromatic ring system of the naphthalenone unit is approximately perpendicular to the mean plane of the five-membered ring, forming a dihedral angle of 87.51?(5)°. An intra-molecular C-H?O hydrogen bond is observed. In the crystal, pairs of C-H?? inter-actions link the mol-ecules, forming inversion dimers.

1,8-Bis(4-chloro-benzo-yl)-7-meth-oxy-naphthalen-2-ol ethanol monosolvate.

Project description:In the title compound, C(25)H(16)Cl(2)O(4)·C(2)H(6)O, the two 4-chloro-benzoyl groups are in syn orientations with respect to the naphthalene ring system and are approximately parallel to each other: the dihedral angle between the benzene rings is 11.43 (16)°. The conformation around each of the carbonyl C-(C=O)-C groups forms a larger angle to the plane of the naphthalene ring system than that to the benzene ring; the angles of the C=O bond vector with the naphthalene ring system and the benzene ring are 55.4 (3) versus 13.5 (3)° and 52.2 (3) versus 17.9 (3)°. An intra-molecular O-H⋯O=C hydrogen bond generates a six-membered ring. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds including the ethanol solvent mol-ecule are observed. A C-H⋯O inter-action also occurs. The ethyl group of the ethanol mol-ecule is disordered over two positions with site occupancies of 0.63 and 0.37. The crystal studied was an inversion twin.

[2,7-Dimeth-oxy-8-(4-meth-oxy-benzo-yl)naphthalen-1-yl](4-meth-oxy-phen-yl)methanone chloro-form monosolvate.

Project description:In the title compound, C28H24O6·CHCl3, the two 4-meth-oxy-benzoyl groups at the 1- and 8-positions of the naphthalene ring system are aligned almost anti-parallel, the benzene rings making a dihedral angle of 25.76?(7)°. The naphthalene ring system makes dihedral angles of 72.51?(7) and 73.33?(7)° with the benzene rings. In the crystal, the naphthalene mol-ecules are linked by C-H?O inter-actions, forming a helical chain along the b-axis direction. A C-H?Cl inter-action is also observed between the aroylated naphthalene and chloro-form mol-ecules. The chloro-form mol-ecule is disordered over two positions with site occupancies of 0.478?(5) and 0.522?(5).

Aggregation-Free Organic Dyes Featuring Spiro[dibenzo[3,4:6,7]cyclohepta[1,2-<i>b</i>]quinoxaline-10,9'-fluorene] (SDBQX) for Dye-Sensitized Solar Cells.

Project description:Three novel organic dyes coded as FHD4-1, FHD4-2, and FHD4-3 featuring spiro[dibenzo[3,4:6,7]cyclohepta[1,2-b]quinoxaline-10,9'-fluorene] (SDBQX) moieties are designed to inhibit dye aggregation to improve the performance of dye-sensitized solar cells (DSSCs). The consistent absorption onsets of FHD4-1, FHD4-2, and FHD4-3 in solutions and adsorbed on TiO2 films indicate that these dyes are aggregation-free dyes. Therefore, coadsorption with chenodeoxycholic acid (CDCA) of these three dyes reduces the performance of DSSCs because no inhibition effect for dye aggregation is needed, but, on the contrary, the dye loading amount is reduced after addition of CDCA.

2,9-Dimethyl-6H,13H-5:12,7:14-dimethano-dibenzo[d,i][1,3,6,8]tetraazecine.

Project description:In the title structure, C(18)H(20)N(4), the aromatic rings are almost orthogonal [81.6?(2)°]. The mol-ecule has symmetry 2 since it is situated on a crystallographic twofold axis. There are only weak inter-molecular inter-actions present in the structure, notably C-H??-electron ring inter-actions. The (1)H and (13)C NMR spectra are in accordance with the X-ray structure analysis.

2-{2,4,6-Tris(bromo-meth-yl)-3,5-bis-[(1,3-dioxoisoindolin-2-yl)meth-yl]benz-yl}iso-indoline-1,3-dione toluene monosolvate.

Project description:In the title compound, C36H24Br3N3O6·C7H8, the toluene solvent mol-ecule is associated with the receptor mol-ecule via C-H⋯π bonding. The planes of the phthalimido groups are inclined at 77.0 (1), 63.0 (1) and 77.8 (1)° with respect to the benzene ring. The mol-ecular conformation is stabilized by C-H⋯O and C-H⋯Br hydrogen bonds. The crystal structure features non-classical hydrogen bonds of the C-H⋯N, C-H⋯O and C-H⋯Br type, leading to a three-dimensional cross-linking of molecules. The pattern of non-covalent inter-molecular bonding is completed by O⋯Br halogen bonds [3.306 (3) Å], which link the receptor mol-ecules into infinite strands extending along the a-axis direction.

(Z)-Ethyl 2-hy-droxy-4-oxo-4-(1,4,5,6,8-penta-meth-oxy-naphthalen-2-yl)but-2-enoate.

Project description:The title compound, C21H24O9, crystallizes with two independent mol-ecules in the asymmetric unit which are almost centrosymmetrically related to each other. The ethano-ate group in one of the two mol-ecules is disordered over two positions with a site-occupation factor of 0.880?(7) for the major occupied site. In the crystal, the 1,3-diketone group exists in the keto-enol isomeric form due to the stabilizing effect of the intra-molecular O-H?O hydrogen bond present in this form. The compound packs as a layered structure in which C-H?? and C-H?O inter-actions are present within and between the layers.

2',7'-Di-bromo-spiro-[cyclo-propane-1,9'-fluorene].

Project description:In the title compound, C15H10Br2, each mol-ecule is situated on special postion mm, so the asymmetric unit contains one-quater of a mol-ecule. The 2,7-di-bromo-9H-fluorene fragment and three spiro-cyclo-propane C atoms lie on different planes, which are perpendicular to each other. In the crystal, ?-? inter-actions between aromatic rings [inter-centroid distance = 3.699?(3)?Å] pack the mol-ecules into stacks extending in [001].

(2E,5E)-2,5-Bis(4-hy-droxy-3-meth-oxy-benzyl-idene)cyclo-penta-none ethanol monosolvate.

Project description:In the title structure, C21H20O5·C2H5OH, the curcumine-type mol-ecule has a double E conformation for the two benzyl-idene double bonds [C=C = 1.342 (4) and 1.349 (4) Å] and is nearly planar with respect to the non-H atoms (r.m.s. deviation from planarity = 0.069 Å). The two phenolic OH groups form bifurcated hydrogen bonds with intra-molecular branches to adjacent meth-oxy O atoms and inter-molecular branches to either a neighbouring mol-ecule or an ethanol solvent mol-ecule. The ethanol O atom donates a hydrogen bond to the keto O atom. These hydrogen bonds link the constituents into layers parallel to (101) in the crystal structure.

Project description:The title compound, C26H22N5O4P3·C3H6O, has been achieved in a two-step synthesis that does not require chromatography. This mol-ecule contains a seven-membered spiro-cyclic ring at two P-atom positions and a five-membered ring containing new P-N bonds at the other P-atom position. Endocyclic torsion angles about the central biphenyl C-C bonds are -41.5?(3) and -44.4?(3)°, and P-N bonds of the central P3N3 ring are within the range 1.5665?(17)-1.6171?(17)?Å, while the P-O distances are in the range 1.5940?(14)-1.6041?(14)?Å. One N-H group makes an inter-molecular N-H?N hydrogen bond, forming centrosymmetric dimers, while the other N-H group makes an N-H?O hydrogen bond to the acetone solvent mol-ecule. The crystal was a two-component non-merohedral twin with ratio 0.811/0.189.
