Copper ammonium complex typically refers to coordination compounds formed between copper ions and ammonia. In these complexes, copper (usually in the +2 oxidation state) acts as the central metal ion, surrounded by ammonia molecules acting as ligands. The typical geometry of such complexes is square planar or tetrahedral, depending on the number of ammonia molecules coordinating and the specific environmental conditions. These complexes often exhibit distinctive blue to deep blue colors, which are commonly used in qualitative inorganic analysis to identify the presence of copper ions. The formation of these complexes involves the displacement of water molecules originally coordinated to the copper ion by ammonia.
