The reaction of Cu(II) salts with 2,6-bis[bis(2-pyridylmethyl)aminomethyl]-4-t-butylphenol (Lt-Bu-OH) afforded two bridged-phenoxido/hydroxido complexes. The dinuclear bridged acetate species [Cu-2(mu-Lt-Bu-O) (mu-CH3COO)](PF6)(2) (1) and the 1D polymeric doubly-bridged-chlorido {[Cu-2(mu-Lt-Bu-OH)(mu-Cl)(2)](ClO4)(2)center dot 4H(2)O}(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.
