Nine new potential polydentate hybrid organotellurium ligands, namely bis(2-aminoethyl)telluride and ditelluride (1,3), bis(2-dimethylaminoethyl)telluride and ditelluride (2,4), 2-(dimethylamino)ethyl aryl telluride (5), 2-methoxyethyl aryl telluride (6), bis(2-aryltelluroethyl)ether (7), 1,2-bis(2-aryltelluroethoxy)ethane (8) and N,N,N',N'-tetrakis(2-aryltelluroethyl)ethane-1,2-diamine (9), (where aryl = 4-MeO-C6H4), have been made in 60-85percent yield by the reaction of Na2Te/Na2Te2 or ArTe-Na+ with the appropriate organic halide.Compounds 6-8 cannot be stored for more than a week and undergo aerial oxidation to give R2TeO species.All the compounds 1-9 have been characterized by molecular weight determination, elemental analyses and 1H NMR and 13C<1H> spectroscopy.Keywords: Tellurium; Polydentate ligands; Diorganotellurides; Diorganoditellurides
