Selenide iodide

The selenide iodides are chemical compounds that contain both selenide ions (Se²⁻) and iodide ions (I⁻) and one or metal atoms. They are in the class of mixed anion compounds or chalcogenide halides.^[1]

Some related compounds do not actually contain a selenide ion, instead containing an iodoselenium cation. These cations include SeI₃⁺, Se₂I₄²⁺, Se₆I₂²⁺, and polymeric Se₆I⁺.^[2]
