Phen-yl(2,4,5-triphenyl-cyclo-penta-1,4-dien-1-yl)methanone.

ABSTRACT: The title compound, C(30)H(22)O, does not form face-to-face ?-? inter-actions despite the presence of four phenyl rings within the compound. Instead weak C-H?? inter-actions occur between adjacent mol-ecules, with C?C contact distances in the range 3.633?(4)-3.974?(4)?Å. The ketone O atom also takes part in a weak C-H?O inter-action. The three pendant phenyl rings are twisted relative to the central cyclopentadiene ring by 17.82?(17), 29.63?(14) and 61.57?(9)°, while the phenylmethanone is nearly orthogonal, the angle between planes being 87.77?(9)°.

The title compound, C(30)H(22)O, does not form face-to-face π-π inter-actions despite the presence of four phenyl rings within the compound. Instead weak C-H⋯π inter-actions occur between adjacent mol-ecules, with C⋯C contact distances in the range 3.633 (4)-3.974 (4) Å. The ketone O atom also takes part in a weak C-H⋯O inter-action. The three pendant phenyl rings are twisted relative to the central cyclopentadiene ring by 17.82 (17), 29.63 (14) and 61.57 (9)°, while the phenylmethanone is nearl ...[more]

Project description:There are three mol-ecules in the asymmetric unit of the title compound, C(23)H(26)O(7), in which the dihedral angles between two benzene rings are 4.34?(9), 18.11?(8) and 8.54?(8)°. The central penta-1,4-dien-3-one fragment makes dihedral angles of 3.95?(9) and 3.32?(16)° with the two adjacent benzene rings in one mol-ecule, whereas the corresponding pairs of angles in the other two mol-ecules are 10.34?(9)/17.46?(8)° and 7.87?(8)/13.33?(8)°. In the crystal, mol-ecules are linked by inter-molecular C-H?O and C-H?? weak inter-actions into a three-dimensional network. Finally, ?-? inter-actions [centroid?centroid distances = 3.5984?(10) and 3.5545?(10)?Å] are observed.

(3-Chloro-phen-yl){2-eth-oxy-5-[(Z)-hydroxy(phen-yl)methyl-idene]cyclo-penta-1,3-dien-1-yl}methanone.

Project description:The title compound, C(21)H(17)ClO(3), which crystallizes as one of two possible oxo/hy-droxy-fulvene prototropic tautomers, possesses a strong intra-molecular O-H?O hydrogen bond that closes a seven-membered ring. The dihedral angles between the central five-membered ring and two pendant rings are 55.05?(9) and 44.51?(10)°. The crystal packing is characterized by weak inter-molecular C-H?O inter-actions between an H atom of the oxymethyl-ene unit and the carbonyl group of an adjacent mol-ecule, resulting in formation of chains of mol-ecules along the a axis.

Project description:The dinuclear title complex, [Ti(2)(C(10)H(15))(2)(C(7)H(2)F(5)O)(4)O], features two Ti(IV) atoms bridged by an O atom.
