Abstract: The title compound, dicaesium tetrathiotungstate(VI), was obtained from a dilute aqueous solution containing equimolar quantities of Cs2CO3 and (NH4)2[WS4]. The compound crystallizes in the orthorhombic space group Pnma and is isotypic with Cs2[MoS4], Rb2[WS4], (NH4)2[WS4] and K2[MoS4]. The structure contains discrete slightly distorted tetrahedral [WS4]2- anions (m symmetry), separated by Cs+ cations. One of the two unique Cs+ cations (both located on mirror planes) is surrounded by nine S atoms and the other by ten S atoms.
