The crystal structure of the silver perchlorate–dioxane complex, AgClO₄.3C₄H₈O₂

Abstract

The structure of the crystalline complex formed by silver perchlorate with three molecules of dioxane has been determined.The crystals are cubic (a 0 ---7.67A) with Laue symmetry m3m and probable space group Pm3m ; there is one molecule of the complex in the unit cell.The silver atoms, at the corners of the cube, are surrounded by a regular octahedron of dioxane oxygen atoms at a distance of 2.46 A. Both the perchlorate ion, whose center is at (½, 1 ~, 2), and the dioxane molecules, which lie along the axes of the unit cube, appear to be rotating with little or no hindrance.Comyns & Lucas (1954) have recently characterized a crystalline complex of silver perchlorate with three molecules of dioxane.An investigation of the structure of this complex was deemed worthwhile because of both the general complex-forming ability of silver ion and the especially remarkable complexing properties of silver perchlorate (Sidgwick, 1950).
