(DmephTe)2 (dmeph = 2,6-dimethylphenyl) reacts with resublimed iodine or with pyridinium iodide under Ar atmosphere to yield [RTeI}RTeI3}]n (1), [R2Te−TeIR] (2), (PyH)[RTeI2] (3) and (PyH)n[RTeI(μ-I)TeIR]n (4) (R = dmeph; Py = pyridine). While mesityl species analogue to 2 and 3 have been already described, the compounds 1 and 4 represent the first organotellurium iodides of their classes reported
