Zinc Selenocyanate, Zn(CNSe)₂

Zinc Selenocyanate Zn(CNSe)₂, may be obtained by dissolving either the metal or its oxide in selenocyanic acid. It forms groups of prismatic needles, which are not deliquescent. By the action of selenium on a solution of zinc cyanide in liquid ammonia, the compound Zn(CNSe)₂.4NH₃ has been obtained. Similar compounds of magnesium and aluminium have also been described.
