I've seen a paper by Sikalov [1] that says that $\ce{IH3}$ and $\ce{IH5}$ should be observable. Has anyone actually tried to synthesize such molecules?

    $\begingroup$ Under high pressure, maybe? Also is there a reason to put iodine first not hydrogen as in ordinary hydrogen iodide? $\endgroup$ – Oscar Lanzi Dec 13 '19 at 15:46

    $\begingroup$ Oscar Lanzi , in this case, some of Hydrogen atoms are negatively charged. That's probably why the author uses such notation. $\endgroup$ – Mr.X Dec 13 '19 at 16:29
