Platinum(IV) iodide is a inorganic compound with the formula PtI4. [1] A dark brown diamagnetic solid and is one of several binary iodides of platinum.
Platinum(IV) iodide can be prepared from the effect of iodine on platinum: [2]
It can also be obtained from the decomposition of hydrogen hexaiodoplatinate(IV) at 80 °C:
Platinum(IV) iodide forms dark brown crystals of several modifications: [3]
Platinum(IV) iodide decomposes in water. It is also soluble in ethanol, acetone, alkali, HI, KI, liquid NH3. [5]
It decomposes when heated:
When dissolved in hydroiodic acid, platinum(IV) iodide forms hydrogen hexaiodoplatinate(IV):
