Synthesis and structure

Tantalum pentaiodide forms from the reaction of metallic tantalum with excess iodine.

It can also be prepared by heating tantalum pentoxide with aluminium triiodide:[1]

Its structure has been verified by X-ray crystallography, which reveals an edge-shared bioctahedral structure, as observed for many pentahalides of Nb and Ta.[2]
