4-[(2,4-Dichlorophenyl)carbamoyl]butanoic Acid

The synthesis and spectroscopic characterization of the glutaric acid-amide derivative, 2,4-Cl2C6H3N(H)C(=O)(CH2)3C(=O)OH (1), are described. X-ray crystal structure determination (1) shows backbone molecule to be kinked about methylene-C–N(amide) bond as seen in C(p)–N–C(m)–C(m) torsion angle ?157.0(2)°; m = methylene p phenyl. An additional twist is noted between amide phenyl groups reflected C(m)–N–C(p)–C(p) 138.2(2)°. most prominent feature molecular packing formation supramolecular tapes assembled through carboxylic acid-O–H…O(carbonyl) amide-N–H…O(amide) hydrogen bonding.
