The title compound, C₃₁H₄₆NO₇⁺·Cl⁻, was synthesized by a one-pot Mannich condensation reaction. In the molecule, the piperidinone ring adopts a chair conformation, and the trimethoxy-substituted benzene rings and octyl chain are arranged equatorially. In the crystal, centrosymmetric dimers are linked into layers parallel to (011) by N—H⋯Cl and C—H⋯Cl hydrogen bonds. A Hirshfeld surface analysis indicates that the most important contributions for the crystal packing are O⋯H (20.5%) interactions followed by C⋯H (7.8%), Cl⋯H (5.5%), C⋯C (1.2%), C⋯O (0.5%) and Cl⋯O (0.4%) interactions.

Keywords: crystal structure; piperidine-4-one; Mannich reaction; Hirshfeld surface analysis.

1. Chemical context

Piperidine is a naturally occurring bioactive alkaloid (Hu et al., 2002 ; Finke et al., 2001 ; Taniguchi & Ogasawara, 2000 ) and the heterocyclic six-membered nitrogen-containing piperidine ring is an essential structural part of many important drugs including paroxetine, raloxifene, haloperidol, droperidol and minoxidiln (Wagstaff et al., 2002 ). 2,6-Diphenyl-substituted piperdine-4-one derivatives are important because of their potential biological activities such as antitumor, antimicrobial, analgesic, local anesthetic, antidepressant and anti-inflammatory (Kálai et al., 2011 ; Leonova et al., 2010 ; El-Subbagh et al., 2000 ; Jerom & Spencer, 1988 ). This wide range of biological activities prompted us to synthesize novel 2,6-diphenyl piperdine-4-one derivatives with enhanced biological activities. In a continuation of this work, the title compound was synthesized using a one-pot Mannich condensation reaction as reported by Noller & Baliah (1948 ). The adopted one-pot reaction is convenient, simple, easy way for separation of the product with possible high yield. A Hirshfield surface analysis of the title compound was carried out in order to study how different functionalities can affect the crystal packing.

2. Structural commentary

In the molecule of the title compound (Fig. 1), the heterocyclic six-membered 4-piperidone ring (N1/C2–C6) adopts a chair conformation, with puckering parameters Q = 0.5750 (15) Å, θ = 13.60 (14)° and φ =5.55 (61)°. The octyl chain at C3, and the trimethoxy-substituted benzene rings attached at C2 and C6 are equatorially oriented. The trimethoxy benzene rings C7–C12 and C13–C18 form a dihedral angle of 73.91 (5)°, and are tilted with respect to the mean plane of the piperidone ring by 59.42 (4) and 78.54 (6)°, respectively. The C13—C2—C3—C22 and O4—C4—C3—C22 torsion angles are 56.36 (17) and −11.0 (2)°, respectively.

3. Supramolecular features

In the crystal, centrosymmetrically-related molecules are linked into dimers through pairs of N—H⋯O hydrogen bonds (Table 1) forming rings with an R₂²(16) graph-set motif. The dimers are further connected by N—H⋯Cl and C—H⋯Cl hydrogen interactions, forming layers parallel to the (011) plane (Fig. 2).

4. Hirshfeld surface analysis

A quantitative analysis of all type of interactions in the title compound was performed using Hirshfeld surface analysis. The Hirshfeld surface mapped over d_norm (Spackman & Jayatilaka, 2009 ) is shown in Fig. 3 where the red areas on the surface indicate short contacts (as compared to the sum of the van der Waals radii), while the blue areas indicate longer contacts and white areas indicate contacts with distances equal to the sum of the van der Waals radii. Two-dimensional fingerprint plots are shown in Fig. 4 with a broad hump showing H⋯H contacts and intense spikes indicating a strong O⋯H interaction, while the broadening in the wing of the C⋯H interaction is due to the presence of a Cl⋯H interaction·The largest contribution is from H⋯H interactions (64.1%), followed by O⋯H interactions, contributing 20.5%. Other weak intermolecular interactions are: C⋯H (7.8%), Cl⋯H (5.5%), C⋯C(1.2%), C⋯O (0.5%) and Cl⋯O (0.4%).

5. Database survey

A search of the Cambridge Crystallographic Database (CSD version 5.39, updates February 2018; Groom et al., 2016 ) revealed three examples of organic compounds having piperdine-4-one as the central unit, namely 1-acryloyl-3-methyl-2,6-bis(3,4,5-trimethoxyphenyl)piperidine-4-one (Gnanendra et al., 2009 ), N-nitroso-2,6-di(3,4,5-trimethoxyphenyl)-3,5-dimethylpiperidin-4-one (Kumaran, et al., 1999 ) and 1-(2-chloroacetyl)-3-methyl-2,6-bis(3,4,5-trimethoxyphenyl)piperidine-4-one (Lakshminarayana et al., 2009 ). A study of the supramolecular features of these compounds revealed that the crystal lattices are stabilized mainly by C—H⋯O intermolecular interactions, forming two-dimensional networks.

6. Synthesis and crystallization

The title compound was synthesized according to the procedure given in literature (Noller & Baliah, 1948). A mixture of 2-undecanone, (0.206 ml, 1 mmol), 3,4,5-trimethoxybenzaldehyde (0.39 g, 2 mmol) and ammonium acetate (0.077 g, 1 mmol) in ethanol (50 ml) was allowed to reflux for three hours. The progress of reaction was monitored by TLC. After completion of the reaction, the mixture was acidified with dilute hydrochloric acid (5 mL) and the resulting precipitate was collected, washed with an ethanol–ether mixture (1:4 v/v), dried and redissolved in ethanol. Crystals suitable for single-crystal X-ray diffraction analysis were obtained on slow evaporation of the solvent at room temperature.

7. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2. H atoms on methyl, methylene and benzene were positioned geometrically with C—H = 0.95–1.00 Å and constrained to ride on their parent atoms with U_iso(H) = 1.2U_eq(C) or 1.5U_eq(C) for methyl H atoms. A rotating model was used for the methyl groups. The N-bound hydrogen atoms were located in a difference-Fourier map and freely refined.

Special details top

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