    • The extinction coefficient (in THF solution) was determined with 3c, because its stability was greater than that of 3a. Intense pyridine-to-metal charge-transfer bands obscured the presumed bis(μ-oxo)dicopper band at about 300 nm.

    • Syn and anti isomers of 3 that differ with respect to the relative position of the imine and amine donors of the two ligands are possible, but we favor the anti form drawn in Scheme 1 because molecular models suggest that steric clashes between arene rings prohibit adoption of a syn geometry. Consistent with this idea, a preliminary crystal structure of a bis(μ-hydroxo)dicopper(II) complex ligated to 2a has the anti conformation (P. L. Holland, W. B. Tolman, unpublished results).
