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