The reactions of Ar2TeO (Ar = 4-MeO-C6H4) with 2-, 3- and 4-pyridine carboxylic acids (LH) afforded different organotelluroxane structural types depending on the stoichiometry of the reactants and the conditions of the reaction. Ar2Te(L)OH (1a–1c) are formed in a 1:1 reaction of Ar2TeO with LH in the presence of water. On the other hand a 1:2 reaction under anhydrous conditions leads to the formation
