2-Ethylpiperidinium chloride

In the title molecular salt, C7H16N+·Cl−, the piperidinium ring adopts a chair conformation. In the crystal, the two components are connected by N—H⋯Cl and C—H⋯Cl hydrogen bonds, forming a supramolecular double-chain structure along the c axis.

In the title molecular salt, C 7 H 16 N + ÁCl À , the piperidinium ring adopts a chair conformation. In the crystal, the two components are connected by N-HÁ Á ÁCl and C-HÁ Á ÁCl hydrogen bonds, forming a supramolecular double-chain structure along the c axis.
Drops of benzylchloride (0.01 mol, 1.0 g) dissolved in THF was then added. The reaction mixture was refluxed for 30 min.
The precipitate formed was washed with THF. The precipitate was then dissolved in methanol at room temperature. After few days, colourless needle-shaped crystals were formed by slow evaporation.
Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes.
Refinement. Refinement of F 2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F 2 , conventional R-factors R are based on F, with F set to zero for negative F 2 . The threshold expression of F 2 > 2σ(F 2 ) is used only for calculating Rfactors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F 2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
