The syntheses and the structural characterization of the compounds [(mes)2Te–Te(I)mes], (PyH)[mesTeI3(I3)] (mes = mesityl = 2,4,6-trimethylphenyl; Py = pyridine), (PyH)3[dmephTeI2(I2)]2(I3) (dmeph = 2,6-dimethylphenyl), (PyH)2[RTeI4]2·(CH3)CO(CH3)·C6H5CH3 (R = p-tert-butylphenyl) and (PyH)2[PhTeI4]2 (Ph = phenyl) are presented. Some earlier analog preparations are compared and the influence of ortho substituents in the aryl group on the oxidation state of tellurium is discussed, as well as the observed conditions for the formation of poly-iodides chains.
Graphical abstractSynthetical and structural features of [(mes)2Te−Te(I)mes], (PyH)[mesTeI3(I3)] (mes = mesityl = 2,4,6-trimethylphenyl; Py = pyridine), (PyH)3[dmephTeI2(I2)]2(I3) (dmeph = 2,6-dimethylphenyl), (PyH)2[RTeI4]2·(CH3)CO(CH3)·C6H5CH3 (R = p-tert-butylphenyl) and (PyH)2[PhTeI4]2 (Ph = phenyl) are discussed. Ortho substituents in the aryl group promote the oxidation state +2 on tellurium atom.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Synthesis and X-ray structural studies of five new organyltellurenyl iodides. ► Influences of aryl-ortho substituents on the oxidation state of tellurium. ► Observed conditions for the achievement of poly-iodide chains.
