The synthesis and structural characterisation of two polynuclear hafnium(IV) complexes
چکیده انگلیسی

Attempts to form extended supramolecular structures incorporating hafnium(IV) complexes of p-sulfonatocalix[6]arene resulted in the serendipitous formation of two polynuclear-hafnium clusters. Subsequent reaction between hafnium triflate and 1 M sulfuric or p-toluenesulfonic acid solutions also led to the formation of the same clusters, identified as cations based on Hf17 and Hf4, respectively.

Addition of 1 M sulphuric or p-toluenesulfonic acid solutions to hafnium(IV) triflate resulted in the formation of two polynuclear hafnium clusters based on either Hf17 (shown) or Hf4 cations. The latter of the two cations was found to interact with p-toluenesulfonate anions to form a bi-layer type arrangement reminiscent to that of p-sulfonatocalix[4]arene.Figure optionsDownload as PowerPoint slide
