Silver sulfonamides can be successfully recrystallized from strong ammonia solution. The spectral characterization of silver sulfadiazine, silver sulfamethazine, silver sulfanilamide, and silver sulfapyridine indicates that the silver sulfonamide formed on reaction of silver nitrate with the free sulfonamide or its sodium salt is correctly represented by a classical salt structure. Complexations of silver sulfonamides with morpholine yield 1:1 crystalline complexes, which can be analyzed by NMR spectroscopy directly. Spectral studies of the silver sulfonamides were carried out using an indirect NMR technique.
