Abstract
The new compound [K(Crypt-2.2.2)]2I12 has been prepared by the reaction of [K(Crypt-2.2.2)]I with iodine in a mixture of ethanol and dichloromethane. It crystallizes in the triclinic space group PĪ with a = 1201,5(5), b = 1213,4(5), c = 1432,1(2) pm, α = 69,11(2), β = 72,01(2), γ= 61,93(3) and Z = 1. The crystal structure has been refined to RF = 0.030 for 2882 reflections. The structure may be described as a layerlike packing of I12 2- anions and [K(Crypt-2.2.2)]+ cations. The anion with point symmetry Ci consists of two pentaiodide groups and a bridging iodine molecule.Keywords
