The solvates of o-acetamidobenzamide

A series of six solvates of o-acetamidobenzamide have been prepared and characterized by single crystal X-ray diffraction. With the exception of the chloroform solvate, five of these, the 1-propanol, 1-butanol, 2-butanol, 1,2-dichloroethane, and 1,4-dioxane solvates are isostructural with similar unit cells and atomic positions for the o-acetamidobenzamide molecules. In all cases, the solvent molecules occupy pores within the hydrogen-bonded sheets of o-acetamidobenzamide. These molecules are readily lost when the crystals are exposed to the atmosphere.
