Abstract

The acid salt of orthoperiodic acid CsH9I2O12crystallizes in the monoclinic system: base-centered unit cell, space group Cc. Unit cell parameters: a=18.473(5) Å, b= 5.439(2) Å, c= 10.481(3) Å, β = 99.73°. The crystal structure consists of layers parallel to the yzcrystallographic axis. The layers are formed by the Cs+ions, the molecules of orthoperiodic acid IO(OH)5, and by the IO2(OH)– 4ions and are joined via hydrogen bonds. The studies of proton conductivity of ceramics reveal their transition into a superionic state at temperatures above 40°C.
