Beschreibungen/Notizen

• Single crystals of potassium dysprosium polyphosphate, KDy(PO3)4, were prepared by the flux method. The title compound crystallizes in structure type IV of KLn(PO3)4 (Ln = lanthanide) compounds. Two helical polyphosphate chains cross the unit cell along [101] with a repeat unit of eight tetrahedra, creating channels where the Dy and K atoms are situated. They have coordination numbers of 8 and 9, respectively.
