The characterization of the previously reported diorganotellurium oxides R2TeO (R = Ph (1) and p-MeOC6H4 (2)) 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 2 revealed a polymeric arrangement that features a zigzag configured Te-O backbone without any secondary Te···O interactions. In solution 1 and 2 exist predominantly as monomers but appear to be in equilibrium with higher oligomers to a minor extent.
