Abstract: Dicaesium bismuth(III) phosphate(V) tungstate(VI), Cs₂Bi(PO₄)(WO₄), has been synthesized during complex investigation in a molten pseudo-quaternary Cs₂O-Bi₂O₃-P₂O₅-WO₃ system. It is isotypic with K₂Bi(PO₄)(WO₄). The three-dimensional framework is built up from [Bi(PO₄)(WO₄)] nets, which are organized by adhesion of [BiPO₄] layers and [WO₄] tetrahedra above and below of those layers. The interstitial space is occupied by Cs atoms. Bi, W and P atoms lie on crystallographic twofold axes.
