K(2)V(2)O(2)(AsO(4))(2)

The vanadium oxide arsenate with formula K(2)V(2)O(2)(AsO(4))(2), dipotassium divanadium(IV) dioxide diarsenate, has been synthesized by solid-state reaction in an evacuated silica ampoule. Its structure is isotypic with K(2)V(2)O(2)(PO(4))(2). The framework is built up from corner-sharing VO(6) oct...

Descripción
Sumario:The vanadium oxide arsenate with formula K(2)V(2)O(2)(AsO(4))(2), dipotassium divanadium(IV) dioxide diarsenate, has been synthesized by solid-state reaction in an evacuated silica ampoule. Its structure is isotypic with K(2)V(2)O(2)(PO(4))(2). The framework is built up from corner-sharing VO(6) octa­hedra and AsO(4) tetra­hedra, creating an infinite [VAsO(8)](∞) chain running along the a- and c-axis directions. The K(+) cations are located in hexa­gonal tunnels, which are delimited by the connection of the [VAsO(8)](∞) chains.
