The Hf-IV-oxothiocluster, [Hf-4(eta(2)-mu(2)-SAc)(4)(eta(2)-mu(2)-SAc)(2)(eta(2)-mu(2)-BuO)(4)(eta(2)-BuO)(2)(mu(3)-O)(2)], was synthesized by reaction of hafnium butoxide with thioacetic acid. The crystal structure shows the presence of a planar tetranuclear Hf-4 core, in which the metal atoms are mu(3)-O bridged and the thioacetate ligands coordinate the Hf ions both through a bridging and a chelating mode. The structural findings are confirmed by multinuclear NMR spectroscopic data.
