The title compound {octacaesium silicodecatungstate nonahydrate, Cs-8[
SiW10O36].9H(2)O} is the first caesium salt of the heteropolyoxometala
te anion gamma-[SiW10O36](8-). The stability of the well known heterop
olyanion depends on the size of the alkali metal cations. The polyanio
ns are connected into infinite columns by Cs cations.
