[Na(15-crown-5)] 2 S 6  was obtained from Na 2 S 4  und 15-crown-5 in acetonitrile. Its crystal structure was determined by X-ray diffraction with 2968 observed reflexions, R = 0.119. Crystal data: a = 861.4(9), b = 1006(1), c = 2097(1) pm, α = 89.7(1), β = 100.20(8), γ = 114.6(1)°, Ζ = 2, space group Ρ 1̄. The chain-like S 6  2-  ion has transoid conformations, each of its terminal atoms is in contact with one Na +  ion which in turn is coordinated with one crown ether molecule.
