Chemistry of Copper - Chemistry LibreTexts
Forming copper(I) complexes (other than the one with water as a ligand) also stabilizes the copper(I) oxidation state. For example, both [Cu(NH 3) 2] + and [CuCl 2]-are copper(I) complexes which do not disproportionate. The chlorine-containing complex is formed if copper(I) oxide is dissolved in concentrated hydrochloric acid.

PAINITE is a very rare calcium zirconium - Crystal
PAINITE is a very rare calcium zirconium aluminum borate mineral with the chemical formula CaZrAl9(BO3)O15. Its coloring ranges from ruby red, pale reddish orange, brown and pale brownish orange. These colors are similar to the colors of garnets and rubies, which is why painite can easily be mistaken for garnet and ruby.
