The nonbonded electron pairs and high refractive index of the iodate ion have been held responsible for the occurrence of noncentrosymmetric structures of alpha -iodic acid and the iodates of alkali metals, ammonium and thallium(I). Many of these are pyroelectric and piezoelectric materials. As a pa...
