V. Shreevidhyaa Suressh, K. Prathebha, S. Abdul Basheer, S. Ponnuswamy and G. Usha

In the title compound, C₂₀H₂₂ClNO, the piperidine ring has a twist-boat conformation. There is an intramolecular C—H

π interaction involving the two phenyl rings which are inclined to one another by 84.91 (7)°. In the crystal, molecules are linked via C—H

O hydrogen bonds, forming helical chains along [010]. The chains are linked by C—H

π interactions, forming sheets parallel to (100).

Keywords: crystal structure; piperidine; diphenylpiperidine; 2-chloro-ethanone; hydrogen bonding; C—H

π interactions.

Structural commentary top

Piperidine and their derivatives are significant heterocyclic compounds found in natural substances (Jain et al., 2005). They have been observed to exhibit a wide range of biological activities, such as anti-fungal, anti-malarial, anti-bacterial and anti-viral activities (Aridoss et al., 2007; Mobio et al., 1989). They also show a highly favourable antiviral activity against a range of primary HIV-1 isolates (Palani et al., 2002).

The molecular structure of the title compound is illustrated in Fig. 1. The sum of the bond angles around atom N1 is 359.85 (1) °, indicating sp² hybridization. The dihedral angle between the phenyl rings (C5—C10 and C16—C21) is 84.91 (7) °. They are linked by an intramolecular C—H···π interaction (Table 1). The piperidine ring adopts a twist-boat conformation.

In the crystal, molecules are linked via C—H···O hydrogen bonds forming helical chains along [010], see Table 1 and Fig. 2. The chains are linked by C—H···π interactions forming sheets parallel to (100), see Table 1.

Synthesis and crystallization top

A mixture of t-3-methyl-r-2,c-6-diphenylpiperidine (5 mmol), chloroacetyl chloride (20 mmol) and triethylamine (20 mmol) in anhydrous benzene (20 ml) was stirred at rt. The precipitated ammonium salt was filtered and the resulting solution was washed with water and bicarbonate solution (4 × 10 ml). Finally, the benzene solution was dried over anhydrous sodium sulfate and concentrated. The pasty mass was purified by crystallization from pet-ether (333-353 K) and ethyl acetate in the ratio of 95: 5, and yielded colourless block-like crystals.

Refinement top

Crystal data, data collection and structure refinement details are summarized in Table 1. H atoms were positioned geometrically and treated as riding on their parent atoms: C—H = 0.93 - 0.98 Å, with U_iso(H)= 1.5 U_eq(C) for methyl H atoms and = 1.2U_eq(C) for other H atoms.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

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.
