Redetermination of AgPO(3)

Single crystals of silver(I) polyphosphate(V), AgPO(3), were prepared via a phospho­ric acid melt method using a solution of Ag(3)PO(4) in H(3)PO(4). In comparison with the previous study based on single-crystal Weissenberg photographs [Jost (1961 ▶). Acta Cryst. 14, 779–784], the results were mainl...

Sumario:Single crystals of silver(I) polyphosphate(V), AgPO(3), were prepared via a phospho­ric acid melt method using a solution of Ag(3)PO(4) in H(3)PO(4). In comparison with the previous study based on single-crystal Weissenberg photographs [Jost (1961 ▶). Acta Cryst. 14, 779–784], the results were mainly confirmed, but with much higher precision and with all displacement parameters refined anisotropically. The structure is built up from two types of distorted edge- and corner-sharing [AgO(5)] polyhedra, giving rise to multidirectional ribbons, and from two types of PO(4) tetra­hedra linked into meandering chains (PO(3))(n) spreading parallel to the b axis with a repeat unit of four tetra­hedra. The calculated bond-valence sum value of one of the two Ag(I) ions indicates a significant strain of the structure.
