| Carbonyl Platinum Thiocyanate, Pt(CNS)2.CO. - A double salt of this substance with potassium thiocyanate, namely, Pt(CNS)2.CO.KCNS, is obtained by adding a solution of potassium thiocyanate to one of carbonyl platinum dichloride in hydrochloric acid until the precipitate first formed is redissolved. On evaporation in the cold it crystallises in yellow needles, which decompose on warming with water. |
