| Abstract: | The reaction of Cu(II) salts with 2,6-bisbis(2-pyridylmethyl)aminomethyl]-4-t-butylphenol (Lt-Bu-OH) afforded two bridged-phenoxido/hydroxido complexes. The dinuclear bridged acetate species Cu2(μ-Lt-Bu-O)(μ-CH3COO)](PF6)2 (1) and the 1D polymeric doubly-bridged-chlorido {Cu2(μ-Lt-Bu-OH)(μ-Cl)2](ClO4)2·4H2O}n (2). The two complexes were structurally characterized. Both complexes revealed ferromagnetic interactions; moderate in complex 1 (J = + 30.8 cm? 1) and very weak (J = + 2.25 cm?1) in 2. |
