To get insights into the chemical properties of mononuclear copper reaction centers with a tetrahedral geometry in copper enzymes, we have developed Cu(II) complexes with the series of halide ion as external ligand [Cu^II(TMG₃tach)(X)]⁺ (X = F^–, Cl^–, Br^–,I^–) by using a tridentate ligand TMG₃tach, consisting with strongly electron donating substituents TMG (tetramethylguanidine) and a rigid cis, cis-1, 3, 5-triaminocyclohexane (tach) framework. In this study, we explored the physicochemical properties and reactivity of the Cu(II) complexes in order to evaluate the effects of halide ligands.
