Abstract
The X-ray crystal structure determination of the glutaric acid-amide derivative, 4-ClC6H4N(H)C(=O)(CH2)(3)C(=O)OH (1), is described. The backbone of the molecule adopts an extended, all-trans configuration but the terminal carboxylic acid and phenyl resides are twisted out of the plane through the bridging atoms, as seen in the torsion angles of O(carboxylic acid)-C(m)-C(m)-C(m) [13.9(5)degrees] and C(m)-N-C(p)-C(p) [47.1(4)degrees]; m = methylene and p = phenyl. The most striking feature of the molecular packing is the formation of supramolecular tapes mediated by carboxylic acid-O-HMIDLINE HORIZONTAL ELLIPSISO(carbonyl) and amide-N-HMIDLINE HORIZONTAL ELLIPSISO(amide) hydrogen bonding.
