Abstract top

In the title molecule, C27H24N2O, the piperidine ring adopts a boat conformation. The acetyl group at position 1 has a bisectional orientation. The two phenyl rings attached to the piperidine ring at positions 2 and 6 have bisectional and axial orientations, respectively, and make a dihedral angle of 75.27 (10)°. The phenylacetonitrile group at position 4 has an equatorial orientation. Molecules are linked by C-H...N, C-H...O intermolecular and C-H...[pi] interactions. A C-H...O intramolecular interaction is also found in the molecule.

Comment top

In the title compound, (Fig. 1), the piperidine ring adopts a boat conformation. The acetyl group at position 1 has a bisectional orientation. The two phenyl rings attached to the piperidine ring at positions 2 and 6 have bisectional and axial orientations, respectively, and make a dihedral angle of 75.27 (10)°. The phenyl-acetonitrile group at position 4 has an equatorial orientation. Molecules are linked by intermolecular C12—H12A···N16, C42—H42···O11 and intramolecular C6—H6···O11 hydrogen bonds. There are C22—H22···π (x, y, z) interactions involving the phenyl ring at 6 and C26—H26···π (1 - x, -y, 2 - z) interactions involving the phenyl ring at C14.

Related literature top

Thiruvalluvar et al. (2007) have reported the crystal structure of (2,6-diphenylpiperidin-4-ylidene)(phenyl)acetonitrile, in which the piperidine ring adopts a chair conformation.

Experimental top

A mixture of (2,6-diphenylpiperidin-4-ylidene)(phenyl)acetonitrile (3.5 g, 0.01 mol), acetic anhydride (2.8 ml, 0.03 mol) and trimethylamine (4.2 ml, 0.03 mol) in benzene (50 ml) was refluxed for 8-10 h. The reaction mixture was cooled to room temperature and poured into ice-cold water. The solid mass was separated by filtration, dried and recrystallized from ethanol. The yield of the isolated product was 2.16 g (55%).

Refinement top

The C-bound H atoms were positioned geometrically and allowed to ride on their parent atoms with C—H = 0.95–1.00 Å and Uiso(H) = 1.2–1.5Ueq(parent atom).

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
