title: Tri-, deca- and dodecanuclear Co(III)-pyrazolate metallacycles.
abstract: Reactions of a Co(III) salt with pyrazoles in the presence of a base have yielded metallacyclic {Co(3)}, {Co(10)} and {Co(12)} species whose structural characterization points to a parallel between analogous carboxylate and pyrazolate motifs.
