First example of a click-reaction on the aminate copper complexes: effect of reaction parameters

The hydrothermal reaction of NaN3 with Cu(Phen)Cl2 in acetonitrile solutions results in the formation of two complexes: new d9 mononuclear cis-[CuII(Phen)2(mtz)2]·H2O and d10 coordination polymer catena-[CuI(Phen)(μ-CN)]n (mtz is 5-methyltetrazolate anion and Phen is 1,10-phenanthroline). The process involves in situ formation of mtz ligand via cycloaddition of acetonitrile and azide (in the case of [CuII(Phen)2(mtz)2]) and cleavage of acetonitrile C–C bond (in the case of [CuI(Phen)(μ-CN)]n). Both complexes were fully characterized by a comprehensive set of methods, including the single crystal X-ray diffraction data.
