All square : The polyinterhalide [Cl(I 2 ) 4 ] − is square‐planar in the crystal structure of [(H 5 O 2 )(I 2 b15c5) 2 ][Cl(I 2 ) 4 ] (I 2 b15c5=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.
