4-Acetamido-anilinium 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 sp2 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.
