Platinum(IV) iodide is ainorganic compound with the formulaPtI4.[1] it is a dark browndiamagnetic solid and is one of several binary iodides of platinum.
Platinum(IV) iodide can be prepared from the effect of iodine on platinum:[2]
Iodide accelerates this process.[3]
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:[4]
Platinum(IV) iodide decomposes in water. It is also soluble inethanol,acetone,alkali, HI, KI, liquidNH3.[6]
It decomposes when heated:
When dissolved inhydroiodic acid, platinum(IV) iodide forms hydrogen hexaiodoplatinate(IV):
