| Abstract |
The first Cu(I) coordination polymer with an aromatic-substituted camphorimine ligand [(CuCl)(mu-Cl) (Cu(H2NC6H4NC10H14O)]n was obtained from reaction of CuCl with 3-(4-aminophenylimino)-1,7,7-trimethylbicyclo[2.2.1]heptan-2-one (H2NC6H4NC10H14O). The electronic and the surface properties (studied by X-ray photoelectron spectroscopy) are consistent with two distinct coordination environments for the copper(I) atomstetrahedral and linearfor the polymer family [(CuCl)(mu-Cl)\Cu(YNC10H14O)\]n. DFT band calculations reveal that the highest energy bands are more localized on the copper(I) tetrahedral sites than on the copper(I) linear sites. The redox properties of [(CuCl)(mu-Cl)\Cu(YNC10H14O)\]n [Y = NMe2 (2b), NH2, and H2NC6H4NC10H14O (2a)] studied by cyclic voltammetry show that the oxidation potentials of the two copper centers are in fact indistinguishable.
