title: K(2)Ho(PO(4))(WO(4)).
abstract: A new compound, dipotassium holmium(III) phosphate(V) tungstate(VI), K(2)Ho(PO(4))(WO(4)), has been obtained during investigation of the K(2)O-P(2)O(5)-WO(3)-HoF(3) phase system using the flux technique. The compound is isotypic with K(2)Bi(PO(4))(WO(4)). Its framework structure consists of flat (∞) (2)[HoPO(4)] layers parallel to (100) that are made up of (∞) (1)[HoO(8)] zigzag chains inter-linked via slightly distorted PO(4) tetra-hedra. WO(4) tetra-hedra are attached above and below these layers, leaving space for the K(+) counter-cations. The HoO(8), PO(4) and WO(4) units exhibit 2 symmetry.
