New insights into the structures of diorganotellurium Oxides. The first polymeric diorganotelluroxane[(p-MeOC6H4)2TEO]n

The characterization of the previously reported diorganotellurium oxides R₂TeO (R = Ph (<b>1</b>) and <i>p</i>-MeOC₆H₄ (<b>2</b>)) was revisited by osmometric molecular weight determinations, ¹²⁵Te NMR spectroscopy, and electrospray spectrometry (ESMS) in solution and by 125Te MAS NMR spectroscopy in the solid state. The single-crystal X-ray structure of <b>2</b> revealed a polymeric arrangement that features a zigzag configured Te-O backbone without any secondary Te···O interactions. In solution <b>1 </b>and <b>2</b> exist predominantly as monomers but appear to be in equilibrium with higher oligomers to a minor extent. <br />
