Bis(benzo-15-crown-5-κ⁵O)strontium bis(triiodide)

Abstract

The title compound, [Sr(C14H20O5)2](I3)2, obtained by slow evaporation of an ethanol/dichloro­methane solution (1:1) of SrCl2, benzo-15-crown-5 and I2, is built of sandwich-like [Sr(benzo-15-crown-5)2]2+ cations and isolated linear I3 − anions which are arranged in alternating layers parallel to (010). The triiodide anions are located in general positions, whereas the cations are located on centres of inversion.
