Single crystals of potassium dysprosium polyphosphate, KDy(PO 3 ) 4 , were prepared by the flux method. The title compound crystallizes in structure type IV of KLn(PO 3 ) 4 (Ln = lanthanide) compounds. Two helical polyphosphate chains cross the unit cell along [101] with a repeat unit of eight tetra

✦ Synopsis
A new polymorph of caesium praseodymium polyphosphate, CsPr(PO 3 ) 4 , features PrO 8 polyhedra sharing O atoms with PO 4 groups, yielding a three-dimensional framework. The latter delimits intersecting channels in which the Cs ions are located.
