The reaction of 18-crown-6, 1,4,7,10,13,16-hexaoxacyclooctadecane, wit
h HgI2/CsI in methanol yields crystals of [Cs-2(C12H24O6)][HgI4] The c
ompound crystallizes monoclinically, space group P2(1)/c, Z = 4, a = 1
574.8(3), b = 1067.0(3), c = 1693.2(6) pm, and beta = 98.29(3)degrees.
The structure consists of a network made up of two different types of
[Cs-(18-crown-6)-Cs](2+) cations, interconnected by [HgI4](2-) anions
. The cations form an ''anti-sandwich'' structure with relatively shor
t Cs ... Cs distances of 382 pm in the first type of cations and a lon
ger distance of 480 pm in the second type of cations.
