From this site:

| Quote: | | Copper cyanide is soluble in ammonium hydroxide, hydrochloric acid, potassium cyanide, and alkali cyanide; and practically insoluble in water,
alcohol, and cold dilute acids. It decomposes at its boiling point, and in nitric acid and boiling dilute hydrochloric acid. |
Note that if you dissolve it in any acid it will release HCN just like any other alkali(ne earth) or metal cyanide. So, I suppose
your best bet would be ammonia solution which, I'm guessing, is possibly due to some complex.
According to the MSDS it is insoluble in cold water. So, it is possible that it is slightly soluble in hot water. This may also release
HCN, by the way.

CuCN is often used in DMF. I don't know if it is entirely soluble in ti, at least partially solvated I suppose. I guess the same thing would stand for
DMSO.
