, p. C5 - C7 (1986)
The synthesis and molecular structure of bis(2-(2-pyridyl)phenyl)tritelluride are described.There is a short Te...N non-bonded interaction of 2.554(7) Angstroem, which may be responsible for the stability of the molecule.The tritelluride can be converted

The synthetic methods available for diorgano tritellurides, which normally give only poor to moderate yields of product, are evaluated.Most reliable when organic groups such as 2-(2'-pyridyl)phenyl- are involved is the reaction of Te2 with the organotellurenyl halide in DMF.Other methods require a final oxidative step.Reactions of Te2-2 with organotellurenyl halides in DMF give deep red solutions which quantitatively deposit tellurium on exposure to air; successful syntheses of (RTe)2Se2 (R=2-(2'-pyridyl or 2'-quinolinyl)phenyl-) were carried out by use of Se2-2 in DMF solution.The air stable bis- tritelluride is reported, and its 125Te and Raman spectral data presented.The role of intra-molecular coordination in stabilising these molecules may be a secondary one; the steric effect of a bulky 2-substituent on the tellurated phenyl-ring may be more significant.Key words: Tellurium; Tritelluride

The syntheses and spectroscopic data (13C n.m.r.) for some new organyltellurium ligands are described.Thus trans metallation of 2-(2-pyridyl)phenyl- (R) or 2-(quinolin-2-yl)phenyl- (R') mercury(II) chloride with TeBr4 gives the organyltellurium tribromide
