Abstract

Abstract Rb[Ag(CN)2] · 0,4H2O was synthesized by reaction of silver cyanide with RbOH and liquid HCN at 0 °C. The colourless crystals are orthorhombic, space group Cmc21, with a = 14.440(3), b = 17.645(1), c = 14.799(1) Å and Z = 32. The structure was solved by Patterson and standard direct methods and refined to R = 0.060 and Rw = 0.051, respectively, for 2204 absorption-corrected unique reflections with F > σ(F). The structure comprises slightly buckled layers of linear [Ag(CN)2]- groups, in which silver atoms are arranged in three- and eight-membered rings. The shortest Ag -Ag distance is 3.05 Å. The rubidium ions are arranged in trigonal-prismatic, cubic and square-antiprismatic sites. Additional cavities contain the water molecules.
