Delocalized mixed-valence Bi- and trinuclear complexes with short Cu-Cu bonds
Two mixed-valence copper complexes were synthesized with ligands N-(2-pyridylmethyl)acetamide (Hpmac) and N,N'-(2-methyl2-pyridylpropan-1,3-diyl)bis(acetamide) (H2pp(ac)(2)). Dimer [CU2(pmac)(2)]OTf and trimer [CU3(pp(ac)(2))(2)]center dot NaOTf both contain fully delocalized, mixed-valence (CuCu1.5)-Cu-1.5 moieties.
