We report a characterization of the high-pressure behavior of zinc-iodate,Zn(IO3)2. By the combination of x-ray diffraction, Raman spectroscopy, andfirst-principles calculations we have found evidence of two subtle isosymmetricstructural phase transitions. We present arguments relating these transitionsto a non-linear behavior of phonons and changes induced by pressure on thecoordination sphere of the iodine atoms. This fact is explained as aconsequence of the formation of metavalent bonding at high-pressure which isfavored by the lone-electron pairs of iodine. In addition, the pressuredependence of unit-cell parameters, volume, and bond is reported. An equationof state to describe the pressure dependence of the volume is presented,indicating that Zn(IO3)2 is the most compressible iodate among those studied upto now. Finally, phonon frequencies are reported together with their symmetryassignment and pressure dependence.
