6-(2-Chloroacetamido)hexanoic acid

Abstract

Crystals of the title compound, C 8 H 14 ClNO 3 , belong to the space group Cc and are characterized by an asymmetric unit containing two molecules, both with a twisted conformation. The molecular packing is stabilized by N-H···O=C hydrogen bonds between the amide groups of molecules with the same conformation. In addition, hydrogen-bonded cyclic carboxylic acid dimers are established between molecules with a different conformation. The ClCH 2 -CONH bond has a cis conformation in order to favour an intramolecular Cl···HN electrostatic interaction. Weak intra- and intermolecular CH 2 ···O=C interactions are also present.
