Abstract
[Cs-4(dibenzo-18-crown-6)(3)](S-6)(2).2CH(3)CN has been prepared from dibenzo-18-crown-6, Cs2CO3 and sulfur in acetonitrile saturated with H 2S. The title compound crystallizes in space group <P(1)over bar> (lat tice dimensions: a = 10,507(7)Angstrom, b = 11,504(6) Angstrom, c = 17 ,792(9) Angstrom, alpha = 97,86(4)degrees, beta = 105,86(4)degrees, ga mma = 101,48(5)degrees) with one formula unit. The crystallographic un its are built of stacks of three crown ether molecules and two hexasul fide chains with the cations located between them. The conformation of the hexasulfide chains is all-cis.
