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

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°. The H atom of the dichloromethyl group is in an eclipsed conformation with respect to the carbonyl group (H—C—C=O = −5°). In the crystal, inversion dimers are linked by p...

Description
Summary:In the title compound, C7H11Cl2NO, the piperidine ring shows a chair conformation and the bond-angle sum at the N atom is 359.9°. The H atom of the dichloromethyl group is in an eclipsed conformation with respect to the carbonyl group (H—C—C=O = −5°). In the crystal, inversion dimers are linked by pairs of C—H...O hydrogen bonds between the dichloromethyl group and the carbonyl O atom, which generate R22(8) loops. The dimers are linked into a ladder-like structure propagating in the [100] direction by short O...Cl [3.1084 (9) Å] contacts.
