| Abstract: | 2-(4-Ethoxyphenlytelluromethyl)tetrahydro-2H-pyran (L1) and 2-(2-{4-ethoxyphenyl}telluroethyl)-1,3-dioxane (L2) have been
synthesized by reacting in situ generated ArTe−Na+ with an appropriate organic halide. The reaction of L1 with iodine results in its diiodo derivative [L1(I)2] (1). The complexes of stoichiometries [CuBrL1] (2), [HgBr2L1] (3) and [RuCl2(p-cymene)·L1/L2] (4/5) are synthesized. The NMR (1H and 13C) in conjunction with elemental analyses, molecular weight and conductance measurements were used to characterize L1, L2, and the complexes 2–5. The ligands coordinate in all the complexes through Te, as indicated by the deshielding of CH2Te signals (up to -0.8 ppm) with respect to those of free ligands, except in the case of 2 in which bonding through CH2O has also to be invoked. Complexes 4 and 5 are characterized structurally (Ru-Te bond length: 2.619(8) and 2.642(1) A, respectively). The Ru-Cl bond lengths are in the range 2.404(3)–2.420(6) A. The Te-C(aryl) bond is shor... |
