Abstract: Palladium (II) and platinum (II) complexes of the chelating ditelluroether ligand, (MeOC6H4Te)2CH2, have been prepared and characterised by IR, UV-Vis and multinuclear (1H, 125Te{1H}, 195Pt{1H}) NMR spectroscopy and chemical analysis. [{Meso-(4-MeOC6H4Te)2CH2} (Ph2PCH2CH2PPh2) Pd(II)] (ClO42 ·4H2O, which crytallizes in the monoclinic system, space group P21/n (No. 14), has the cell parameters a = 19.624(7), B = 12.324(8), C = 21.497 (5) Å, β = 9.227 (2)°, V = 5194(3) Å, Z = 4, R = 0.0746, Rw = 0.0692 and [meso-(4-MeOC6H4Te)2CH2]Pd(II) Cl2, which also crystallizes in the monoclinic system, space group P21/n (No. 14), has the cell parameters a = 7.90(2), B = 20.36(5), C = 11.44(2) Å, β = 100.8(2)°, V = 1806(6) Å3, Z = 4, R = 0.0621, Rw = 0.0650. The immediate environment about tellurium in both compounds is that of the meso invertomer and these are the first reported structures where the chelating ditelluroether had a one-carbon backbone. Only the diastereoisomer was observed in the NMR spectrum of [{meso-4-MeO-C6H4Te)2CH2} (Ph2PCH2CH2PPh2 Pd(II) ] (ClO4)2.
