Packing Diagrams for Sulfapyridine, Sulfapyrindine Dioxane Solvate, and Sulfapyridine THF solvate

We have crystallized sulfapyridine dioxane

solvate and sulfapyridine tetrahydrofuran

solvate and determined the x-ray crystal

structures at 170 K. The unit cell packing

diagram shows a large solvent pocket

occupied by the dioxane and THF solvent

molecules.
