## Abstract A new binucleating bis(terdentate) ligand, 3,5β[3βbis(2βpyridyl)pyrazoleβ1βylmethyl]pyrazole (HL^2^), was synthesized. Reaction of the deprotonated ligand L^2^ with hydrated Cu^II^ salts gives (ΞΌβpyrazolato)(ΞΌβhydroxido)βbridged binuclear and tetranuclear complexes [L^2^Cu~2~(ΞΌβOH)(ClO~
