Abstract

Two Cu^II complexes with the new zwitterionic ligand. 1-carboxymethylpyridinio-3-benzoate (L), [Cu₄L₄(OH) ₂](ClO₄)₂' 8H₂O (1) and [Cu ₄L₄(OH)₂]Cl₂.8H₂O (2), have been synthesized and characterized crystallographically and magnetically. The two compounds contain isostructural chains, in which the anionic basic copper(II) carboxylate clusters [CU₄(μ₃-OH) ₂(RCOO)₈]²-are quadmply interlinked by cationic organic spacers. Magnetic analyses using a tetranuclear model indicate that antiferromagnetic interactions between neighboring copper(II) ions are operative through the double hydroxo bridges and the mixed hydroxo/carboxylato bridges.
