Figure 88.
Partial view (ball-and-stick representation) of the crystal packing of (A) the discrete I42– anion hosted in a size-matched cavity formed by four HMET units, (B) the discrete I73– anion surrounded by four trication units, (C) the discrete I42– anion caged between two N,N′-bis(tetrafluorobenzyl)-(E)-1,2-bis(4,4′-bipyridinium)ethylene units (the cations are disordered over two positions), and (D) the complex containing the discrete pseudolinear dodecaiodide species. Polyiodide anions are represented in space-filling style. Color code: carbon, gray; nitrogen, blue; iodine, purple; fluorine, yellow; hydrogen, white.
