1-Benzyl-3,5-bis-(4-chloro-benzyl-idene)piperidin-4-one.

ABSTRACT: The title compound, C(26)H(21)Cl(2)NO, crystallizes with two symmetry-independent mol-ecules (A and B) in the asymmetric unit. In both mol-ecules, the central heterocyclic ring adopts a sofa conformation. The dihedral angles between the planar part of this central heterocyclic ring [maximum deviations of 0.011?(1) and 0.036?(1)?Å in mol-ecules A and B, respectively] and the two almost planar [maximum deviations of 0.020?(1) and 0.008?(1)?Å in A and 0.007?(1) and 0.011?(1) in B] side-chain fragments that include the aromatic ring and bridging atoms are 20.1?(1) and 31.2?(1)° in mol-ecule A, and 26.4?(1) and 19.6?(1)° in mol-ecule B. The dihedral angles between the planar part of the heterocyclic ring and the benzyl substituent are 79.7?(1) and 53.2?(1)° in mol-ecules A and B, respectively. In the crystal, weak inter-molecular C-H?O hydrogen bonds link the two independent mol-ecules into dimers.

Project description:The inversion-related mol-ecules of the title compound, C(26)H(21)F(2)NO, associate into closed dimeric subunits via co-operative C-H⋯π inter-actions. Two non-classical C-H⋯O and one C-H⋯N intra-molecular hydrogen bonds are also found in the crystal structure. The piperidin-4-one ring adopts a sofa conforamtion with the 1-benzyl group in the equatorial position, and the equiplanar fluoro-phenyl substituents in the 3- and 5-positions stretched out on either side. The 1-benzyl group is disposed towards the substituent in the 6th position of the piperidin-4-one ring. The 3,5-diene units possess E configurations.

Project description:In the title mol-ecule, C(22)H(19)NOS(2), the piperidine ring adopts an envelope conformation with the benzyl substituent in an equatorial position.

Both thio-phene rings are disordered over two orientations [occupancy ratios of 0.799 (1):0.201 (1)] at 180° from one another. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions help to stabilize the packing.

The dihedral angles between the benzene rings in each compound are 21.07?(6)° for (1) and 13.4?(3)° for (2). In both compounds, the piperidinone rings adopt a sofa confirmation and the methyl group attached to the N atom is in an equatorial position. In the crystal of (1), two pairs of O-H?N and O-H?O hydrogen bonds link the mol-ecules, forming chains along [10-1]. The chains are linked via C-H?O hydrogen bonds, forming undulating sheets parallel to the ac plane. In the crystal of (2), mol-ecules are linked by weak C-H?Cl hydrogen bonds, forming chains along the [204] direction. The chains are linked along the a-axis direction by ?-? inter-actions [inter-centroid distance = 3.779?(4)?Å]. For compound (2), the crystal studied was a non-merohedral twin with the refined ratio of the twin components being 0.116?(6):0.886?(6).

Project description:In the title compound C(32)H(31)NO(3), the all-yloxy groups on either side of the piperidin-4-one ring are conformationally disordered.

Flanking phenyl substituents are stretched out on either side of the six-membered ring. ?-? inter-actions with a centroid-centroid distance of 3.885?(1)?Å give rise to mol-ecular dimers and short C-H?? contacts lead to chains along the c axis.
