Resumo

It is demonstrated here that tridentate imine ligands can control the nuclearity of copper(II) complexes based on the donor atoms present in the ligand. The N, N ', N ''-donating imine ligand led to a mononuclear compound, namely dichlorido[N, N-dimethyl-N '-(pyridin-2-ylmethylidene) ethane-1,2-diamine]copper(II) monohydrate, [CuCl2(C10H15N3)]center dot H2O,1, while the N, N ', O-donating imine ligand produced a binuclear metal complex, namely mu(2)-chloridodichlorido(mu(2)-2-{[2-(dimethylamino) ethyl] iminomethyl} phenolato)(N, N-dimethylethylenediamine) dicopper(II) 0.11-hydrate, [Cu-2(C11H15N2O) Cl-3(C4H12N2)] 0.11H(2)O, 2. The structure of 2 is a remarkable example of a binuclear copper(II) complex containing a single substituted 2-iminomethylphenolate ligand that has two copper(II) sites in square-pyramidal coordination.
