4-Hydroxybenzamide 1,4-dioxane hemisolvate

Abstract

The asymmetric unit of the title compound, C7H7NO2·0.5C4H8O2, is composed of one 4-hydroxybenzamide molecule and half of a 1,4-dioxane molecule. The complete dioxin molecule is generated by crystallographic inversion symmetry. The crystal has an extensive system of hydrogen bonds, in which the three donor H atoms are fully utilized: these result in amide–amide homodimers, and N—H...O(dioxane) and O—H...O(amide) links.
