I16 4? Ions in crystalline (theobromine)2.H2I8; X-ray structure of (theobromine)2.H2I8

Abstract

Crystal structure analysis shows that (theobromine)2.H2I8 is a polyiodide salt composed of alternating cationic and anionic layers; the former consist of hydrogen-bonded protonated theobromine species and the latter of I164– polyiodide ions.
