Abstract

Dark-green crystals of [Rb(12-crown-4)(2)]I-5 were obtained by the reaction of stoichiometric amounts of RbI, I-2 and 12-crown-4 from an ethanol/methanol solution (monoclinic space group P2(1)/n with Z = 4, a = 8.9200(10), b = 24.069(2), c = 13.9950(10) angstrom and beta = 91.984(9)degrees). The crystal structure contains one independent formula unit consisting of the polyiodide and the cation. The anionic part of the structure is an isolated, V-shaped pentaiodide I-5(-). The cation is a sandwich complex with two 12-crown-4-molecules surrounding the alkali metal atom.
