Li2Ti(IO3)6was synthesized by combining Li2CO3(0.30 g, 4.06 × 10−3mol), TiO2(0.300 g, 3.76 × 10−3mol), HIO3(5.00 g, 2.84 × 10−2mol), and water (10 mL) in a 23 mL Teflon-lined stainless steel autoclave and heating to 230 °C for 4 days followed by cooling to room temperature at 6 °C/h. The only product from the reaction, clear, colorless crystals of Li2Ti(IO3)6, was washed with water and ethanol and recovered in 91% yield based on TiO2.
