N,N,N',N'-Tetra-kis(2-hydroxy-ethyl)terephthalamide
Abstract:
The mol-ecule of the title compound, C(16)H(24)N(2)O(6), which lies on a crystallographic inversion centre in the centre of the benzene ring, adopts an anti conformation in terms of the relative orientation of two amide carbonyl groups. One pair of the 2-hydroxy-ethyl groups is partially disordered with site occupancy factors of 0.811 (2) and 0.189 (2). The dihedral angle between the amide group and central benzene ring is 67.0 (2)°. Two O-H⋯O and one bifurcated O-H⋯(O,O) hydrogen bonds are present, resulting in a three-dimensional network.

Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
