So, I've gotten really interested in this new paper https://link.springer.com/article/10.1007/s00214-019-2524-0?shared-article-renderer by Alexander Sikalov. It says that most hypervalent halogen hydrides should exist and that the first candidates for observation are IH₃ and IH₅. My question is: have any experimentalists actually attempted to synthesize such molecules?
