2.[1][2][3]
Synthesis
Production of platinum(II) iodide can be by heating of platinum(II) chloride with potassium iodide:
- PtCl2 + 2KI → PtI2 + 2KCl
Chemical properties
Platinum(II) iodide decomposes when heated:[4]
- Ptl2 → Pt + I2
Physical properties
Platinum(II) iodide forms black crystals[5] of several modifications. It is insoluble in water, ethanol, acetone, or ether, but is soluble in ethylamine and hydrogen iodide.[6]
