The HfIV-oxothiocluster, [Hf4(·2-¼2-SAc)4(·2-¼2-SAc)2(·2-¼2-BuO)4(·2-BuO)2(¼3-O)2], was synthesized by reaction of hafnium butoxide with thioacetic acid. The crystal structure shows the presence of a planar tetranuclear Hf4 core, in which the metal atoms are ¼3-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

Abstract
The HfIV-oxothiocluster, [Hf4(·2-¼2-SAc)4(·2-¼2-SAc)2(·2-¼2-BuO)4(·2-BuO)2(¼3-O)2], was synthesized by reaction of hafnium butoxide with thioacetic acid. The crystal structure shows the presence of a planar tetranuclear Hf4 core, in which the metal atoms are ¼3-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 dataFile in questo prodotto:
