Cholest-5-en-7-one
In the deca-hydro-phenanthrenone ring system of the title compound, C(27)H(44)O, the two cyclo-hexane rings adopt chair conformations, whereas the cyclo-hexene ring adopts an envelope conformation. The cyclo-pentane ring is twisted. In the crystal structure, mol-ecules are stacked along the a axis, but no significant inter-molecular inter-actions are observed.
متن کاملA second polymorph of (2E)-1-(4-fluorophenyl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-1-one
The crystal structure of the title compound, C(18)H(17)FO(4), reported here is a polymorph of the structure first reported by Patil et al. [Mol. Cryst. Liq. Cryst. Sci. Technol. Sect. A (2007), 461, 123-130]. It is a chalcone analog and consists of substituted phenyl rings bonded at the opposite ends of a propenone group, the biologically active region. The dihedral angle between the mean plane...
متن کاملSecond monoclinic form of (E)-3-(4-fluorophenyl)-1-phenylprop-2-en-1-one
The unit-cell dimensions and space group of the second monoclinic polymorph of the title compound, C15H11FO, differ from those of the previously reported form [Jing (2009 ▶). Acta Cryst. E65, o2515]. The title compound shows an E conformation of the C=C bond with the 4-fluoro-phenyl group opposite to the benzoyl group. The torsion angle of between the planes of the 4-fluoro-phenyl and benzoyl g...
متن کامل(E)-3-(4-Heptyloxyphenyl)-1-phenylprop-2-en-1-one
In the title compound, C22H26O2, the aromatic rings are inclined to one another by 8.39 (9)° and the mol-ecule has an E conformation about the C=C bond. In the crystal, mol-ecules stack head-to-tail along the b-axis direction. They are linked by very weak C-H⋯O contacts, forming C(4) chains along [100]. Two chains are linked by a pair of very weak C-H⋯O contacts, enclosing inversion-dimeric R 2...
متن کامل1-(4-Chlorophenyl)-4,4-dimethylpent-1-en-3-one
In the title compound, C(13)H(15)ClO, the carbonyl and ethenyl groups are not coplanar with benzene ring system, forming dihedral angles of 35.37 (5) and 36.27 (11)°, respectively. The mol-ecules are packed in an offset face-to-face arrangement showing π-π stacking inter-actions involving the benzene rings [centroid-centroid distance = 3.586 (4) Å].
