**三碘化鋯**是一種鋯的碘化物，化學式 ZrI3。

## 製備

三碘化鋯可以由四碘化鋯和鋯在 500–700 °C 下反應而成。

　
: $\mathrm {3\ ZrI_{4}+Zr\longrightarrow 4\ ZrI_{3}} $

它也可以由鋁還原四碘化鋯而成：

　
: $\mathrm {3\ ZrI_{4}+Al\longrightarrow 3\ ZrI_{3}+AlI_{3}} $

氣態的三碘化鋯可以由鋯和碘化氫在 1100–1500 K 下反應而成。

## 性質

三碘化鋯是一種藍色固體。在 275 °C 下，它會歧化成二碘化鋯和四碘化鋯。三碘化鋯是正交晶系的，空間群 Pmmn (No. 59)，晶格參數 a = 1295.4 pm、b = 667.9 pm 和 c = 729.2 pm。
