Abstract

The title compound was synthesized by a reactive salt reaction at 773 K over a period of 5 d. It has a one-dimensional chain structure consisting of K(+) cations and one-dimensional [Ag(2)Sn(2)Se(6)](2-) anions. The chain is constructed by edge-sharing bitetrahedral [Sn(2)Se(6)] units connected in a 1:2 ratio via linear Ag(+) ions.
