Two classes of iodine-rich salts that consist of iodine-rich cations and iodate (IO3-) or periodate (IO4-) anions were synthesized. The synthesis of analogous I3O8- salts was more difficult because of poor solubility and hydrolytic instability. All iodine-rich salts were fully characterized by infrared, H-1 nuclear magnetic resonance, and C-13 nuclear magnetic resonance spectroscopy as well as elemental analyses. The molecular structures of compounds 15 and 24 were elucidated by X-ray single-crystal diffraction. Additionally, the heats of formation were calculated with Gaussian 03. The detonation properties and biocidal efficiency were calculated and evaluated using CHEETAH 7.
