一氟化碘是化学式为IF的化合物,是互卤化物的一种。一氟化碘在常温下不稳定。

性质

[编辑]

一氟化碘是白色粉末,在−78 °C以下稳定;在−14 °C以上,则歧化五氟化碘

像任何其它互卤化物一样,一氟化碘能与水反应,生成氟化氢以及次碘酸

它和氮化硼在−30 °C的三氯氟甲烷里反应,可以产生纯NI3[1]

BN + 3 IF → NI3 + BF3

它是所有互卤化物中最不稳定的一个,所以要想精确测量它的物理性质是不可能的。

制备

[编辑]

在低温下,可以由碘与直接化合来制得一氟化碘:

尽管如此,这个反应的产率很低,会生成大量的副产物三氟化碘五氟化碘。纯的一氟化碘至今无法制得。因此,它的大部分性质都是未知的。它有可能具有聚合物结构。
