Synthesis and Crystal Structure of Anhydrous Di-iodyl Carbonate (IO₂)₂[CO₃], Hosting I⁵⁺-Cations.

ABSTRACT: The anhydrous di-iodyl carbonate (IO₂)₂[CO₃] has been synthesized in a laser-heated diamond anvil cell at 30(2) GPa and 1600(200) K by a reaction of I₂O₅ with CO₂. Its monoclinic crystal structure (C2/c with Z = 4) was determined from synchrotron single crystal X-ray diffraction data. The experimental structural model was confirmed by density functional theory based calculations in combination with experimental Raman spectroscopy. (IO₂)₂[CO₃]-C2/c belongs to the family of sp²-carbonates, and its crystal structure is characterized by the presence of nearly trigonal-planar [CO₃]^2- groups. In contrast to other iodide-containing
