Crystal structure of 2,2-dichloro-1-(piperidin-1-yl)ethanone

In the title compound, C7H11Cl2NO, the piperidine ring shows a chair conformation and the bond-angle sum at the N atom is 359.9 degrees. The H atom of the dichloromethyl group is in an eclipsed conformation with respect to the carbonyl group (H-C-C=O = -5 degrees). In the crystal, inversion dimers are linked by pairs of C-H center dot center dot center dot O hydrogen bonds between the dichloromethyl group and the carbonyl O atom, which generate R-2(2)(8) loops. The dimers are linked into a ladderlike structure propagating in the [100] direction by short O center dot center dot center dot Cl [3.1084 (9) angstrom] contacts.
