Abstract The title compound AgS 2 CN R 2 was prepared from an aqueous alcoholic solution by reaction of dicyanoargentate [Ag(CN) 2 ] – with excess ammoniumdithiocarbamate. It crystallizes in the tetragonal space group I $\bar{4}$ 2 d (No. 122) with a = 7.9898(4) and c = 12.1072(7) Å, V = 772.89(7) Å 3 , Z = 8. The crystal structure comprises a 3D tetrahedral network of distorted AgS 4 units connected via all vertices thus forming the β‐cristobalite structure type. The dithiocarbaramate ligands extend into the hollow space of the framework. Thermal decomposition starts above 125 °C and proceeds with a complex reaction to give finally Ag 2 S (acanthite).
