Abstract

Cs4(dibenzo-18-crown-6)3](S6)2-2CH3CN has been prepared from dibenzo-18-crown-6, Cs2C 0 3 and suifur in acetonitrile saturated with H 2S. The title compound crystallizes in space group P I (lattice dimensions: a = 10,507(7)Ä, b = 11,504(6) A, c = 17,792(9) A, a = 97,86(4)°, ß = 105,86(4)°, y = 101,48(5)°) with one formula unit. The crystallographic units are built of stacks of three crown ether molecules and two hexasulfide chains with the cations located between them. The conformation of the hexasulfide chains is all-cis.
