Deskripsi

The synthesis and spectroscopic characterization of the glutaric acid-amide derivative, 2,4-Cl<sub>2</sub>C<sub>6</sub>H<sub>3</sub>N(H)C(=O)(CH<sub>2</sub>)<sub>3</sub>C(=O)OH (<b>1</b>), are described. The X-ray crystal structure determination of (<b>1</b>) shows the backbone of the molecule to be kinked about the methylene-C–N(amide) bond as seen in the C(p)–N–C(m)–C(m) torsion angle of −157.0(2)°; m = methylene and p = phenyl. An additional twist in the molecule is noted between the amide and phenyl groups as reflected in the C(m)–N–C(p)–C(p) torsion angle of 138.2(2)°. The most prominent feature of the molecular packing is the formation of supramolecular tapes assembled through carboxylic acid-O–H<sup>…</sup>O(carbonyl) and amide-N–H<sup>…</sup>O(amide) hydrogen bonding.
