  3. Iodine compounds - Wikipedia

    en.wikipedia.org/wiki/Iodine_compounds

    Liquid iodine trichloride conducts electricity, possibly indicating dissociation to ICl + 2 and ICl − 4 ions. [9] Iodine pentafluoride (IF 5), a colourless, volatile liquid, is the most thermodynamically stable iodine fluoride, and can be made by reacting iodine with fluorine gas at room temperature. It is a fluorinating agent, but is mild ...

    en.wikipedia.org/wiki/Fluorine_compounds

    The tetrafluorides show a mixture of ionic and covalent bonding. Zirconium, hafnium, plus many of the actinides form tetrafluorides with an ionic structure that puts the metal cation in an 8-coordinate square antiprism. [58] [59] Melting points are around 1000 °C. [60] Titanium and tin tetrafluorides are polymeric, with melting points below ...

  6. Interhalogen - Wikipedia

    en.wikipedia.org/wiki/Interhalogen

    The covalent bond between the two atoms has some ionic character, the less electronegative halogen, X, being oxidised and having a partial positive charge. All combinations of fluorine, chlorine, bromine, and iodine that have the above-mentioned general formula are known, but not all are stable.

  7. Hypervalent organoiodine compounds - Wikipedia

    en.wikipedia.org/wiki/Hypervalent_organoiodine...

    These iodine compounds are hypervalent because the iodine atom formally contains in its valence shell more than the 8 electrons required for the octet rule. Hypervalent iodine oxyanions are known for oxidation states +1, +3, +5, and +7; organic analogues of these moieties are known for each oxidation state except +7.
