The title compound, potassium silver tetra-niobium nona-oxide arsenate, K(0.8)Ag(0.2)Nb(4)O(9)AsO(4), was prepared by a solid-state reaction at 1183 K. The structure consists of infinite (Nb(2)AsO(14))(n) chains parallel to the b axis and cross-linked by corner sharing via pairs of edge-sharing octa-hedra. Each pair links together four infinite chains to form a three-dimensional framework. The K(+) and Ag(+) ions partially occupy several independent close positions in the inter-connected cavitie ...[more]
