Abstract
A series of copper complexes bearing new 6-substituted tris(2-pyridylmethyl)amine ligands (L(R)) appended with NH(p-R-C(6)H(4)) groups (R = H, CF(3), OMe) were prepared. These ligands are electronically tunable (ΔE(1/2) = 160 mV) and Cu(I)(L(R))(+) complexes react with oxygen to form hydrogen bonded (trans-1,2-peroxo)dicopper species.
