The tetraammine copper(II) complex, also called the cuprammonium complex, is an ionic complex of copper with the formula [Cu(NH3)4(H2O)2]2+.
It has an intense ultramarine blue coloration to the naked eye but when portrayed digitally is somewhat muted in color.
The copper-ammonia complex can be formed by the addition of ammonia to solutions of copper(II) ions, or by dissolving basic copper compounds in aqueous ammonia. The ion is the main constituent of the compounds Schweizer's reagent and tetraammine copper(II) sulfate, among others.
- Tetraaminecopper(II) sulfate
- Dissolve cellulose
The tetraamine copper(II) complex is irritant due to its ammonia. Copper is toxic to humans and much more so to aquatic life.
Depends on the individual amine copper complex.
Treat like any other soluble copper compound.
