4-Acetamidoanilinium nitrate monohydrate

Abstract

In the title hydrated salt, C8H11N2O+·NO3 −·H2O, the N—C bond distances [1.349 (2) and 1.413 (2) Å] along with the sum of the angles (359.88°) around the acetamide N atom clearly indicate that the heteroatom has an sp 2 character. The ammonium group is involved in a total of three N—H...O hydrogen bonds, two of these are with a water molecule, which forms two O—H...O hydrogen bonds. All these hydrogen bonds link the ionic units and the water molecule into infinite planar layers parallel to (100). The remaining two N—H...O interactions in which the ammoniun group is involved link these layers into an infinite three-dimensional network.
