    The compound can also be synthesized by reacting iodine vapor with molten lead between 500 and 700 °C. [18] A thin film of PbI 2 can also be prepared by depositing a film of lead sulfide PbS and exposing it to iodine vapor, by the reaction PbS + I 2 → PbI 2 + S. The sulfur is then washed with dimethyl sulfoxide. [19]
