The synthesis of some new diaryltellurium(IV) dicarboxylates (salicylate, benzoate, cinnamate) and carboxylales (oxalate, o-phthalate, succinate) by the reactions of bis(p-methoxyphenyl)telluroxide and bis(p-hydroxyphenyl)telluroxide with the corresponding carboxylic acid is reported. The resulting carboxylates have been subjected to elemental analyses, conductance and cryoscopic measurements, infra-red and proton magnetic resonance spectral studies. Solution studies reflect the non-ionic nature of these compounds. Infra-red spectral studies predict the unidentate nature of salicylate, benzoate and cinnamate and bidentate nature of oxalate, o-phthalate and succinate groups. A PMR spectral study confirms their proposed stoichiometry. These compounds possess a trigonal bipyramidal structure with a tetra-coordinate central tellurium atom.
