A New Supramolecular Synthon Using <i>N</i> -Methylaniline. The Crystal Structure of the 1 : 1 Adduct of <i>N</i> -Methylaniline with 5-Nitrofuran-2-carboxylic Acid

Abstract

The crystal structure of the 1 : 1 adduct of N -methylaniline with 5-nitrofuran-2-carboxylic acid has been determined by single-crystal X-ray diffraction. Crystals are monoclinic, space group P 21/ c with Z 4 in a cell of dimensions a 8·467(5), b 6·106(2), c 23·95(1) Å, ß 94·48(3)°. The molecules associate in a tetrameric, proton-transfer formation which has potential as a new supramolecular synthon.
