Dipotassium bismuth phosphate tungstate has been synthesized using the flux technique. It crystallizes in the space group Ibca and is isotypic with Na2Y(PO4)(MoO4). It exhibits a layered structure, which is built up from [Bi(PO4)(WO4)]∞2- layers. Each layer is composed of [BiO8]∞ zigzag chains, which are connected via PO4 and WO4 tetrahedra. The parallel anionic [Bi(PO4)(WO4)]∞2- layers are stacked along [100] and are held together by K+ counter-cations which occupy sites in the interlayer space. Bi, W and P atoms are all located on twofold axes. [ABSTRACT FROM AUTHOR]
