Abstract
Dark-green crystals of [Rb(12-crown-4)2]I5 were obtained by the reaction of stoichiometric amounts of RbI, I2 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) Å and β = 91:984(9)°). 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. © 2013 Verlag der Zeitschrift für Naturforschung, Tübingen.
