Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>All square</bold>: The polyinterhalide [Cl(I₂)₄]⁻ is square‐planar in the crystal structure of [(H₅O₂)(I₂b15c5)₂][Cl(I₂)₄] (I₂b15c5=diiodobenzo‐15‐crown‐5), although it would be tetrahedral in the gas phase. Along with other effects, such as electrostatic attractions between the cationic and planar anionic layers, iodine–iodine bonding with σ‐hole interactions plays a considerable role is stabilizing the square‐planar configuration.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4t7bqrtm" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
