  two TeAr, or a TeAr and a Br ligand. Upon mixing two symmetrically substituted Zn(tmeda)(TeAr)2 complexes in solution, 125Te NMR revealed a facile ligand exchange providing Zn(tmeda)(TeAr)(TeAr′). In addition, Zn(tmeda)(TeAr)(TeAr′) complexes form on mixing symmetric Zn(tmeda)(TeAr)2 complexes and (TeAr′)2. The lability of the zinc complexes was put to advantage in ligand‐substitution reactions wherein

  Reactions of [PtCl2((PP)-P-boolean AND)] ((PP)-P-boolean AND = dppm, dppe or dppp) with Pb(SMes)(2) and sodium arylchalcogenolates yielded mononuclear complexes of the type, cis-[Pt(EAr) 2(PXP)] [EAr = EMes (E = S, Se or Te; Mes = mesityl), Sepym (pym = 2-pyrimidyl) or SepymMe(2) (pymMe(2) = 4,6-dimethyl-2-pyrimidyl]. These complexes were characterized by elemental analyses and NMR (H-1, P-31) spectroscopy. The molecular structures of [Pt(SeMes)(2)(dppp)]center dot 1\2C(6)H(6), [Pt(TeMes)(2)(dppp)]center dot 3C(6)H(6), [Pt(SeC4H3N2)(2)(dppm)] and [PtSeC4H(4,6-Me2) N2} 2(dppm)]center dot CH2Cl2 were established by single crystal X-ray diffraction analyses. An attempt has been made to rationalize the NMR data with the nature of chelated bis phosphine ligand, chalcogen atom and aryl substituent on the chalcogen atom. The energy difference (Delta E), calculated by DFT, is very small between various conformers. The calculated Delta E between various conformers of mesitylthiolate dppp complex lies in the range of 0.1- 1.0 kcal/ mol; the same for mesitylselenolate complex lies in the range of 0.5e2.2 kcal/ mol and for mesityltellurolate complex it is in the range of 1.0 - 3.0 kcal/ mol.

  Reactions of orthometallated binuclear palladium complexes with NaER, obtained by NaBH(4) reduction of R(2)E(2) in methanol, gave complexes, [Pd(2)(mu-ER)(2)(C(boolean AND)Y)(2)] (HC(boolean AND)Y= N,N-dimethylbenzylamine (C(6)H(5)CH(2)NMe(2)), N,N-dimethylnaphthylamine (C(10)H(7)NMe(2)), tri-o-tolylphosphine P(tol-o)(3)}; ER= SePh, SeMes, TePh, TeMes (Mes = 2,4,6-Me(3)C(6)H(2)). Similar reactions of [Pd(2)(mu-Cl)(2)(C(10)H(6)NMe(2)-C, N)(2)] with Pb(SMes)(2) or MesSH in the presence of NaHCO(3) gave chloro/thiolato-bridged complex [Pd(2)(mu-Cl)(mu-SMes)(C(10)H(6)NMe(2)-C, N)(2)]. The newly synthesized complexes were characterized by elemental analysis, UV-Vis, IR, NMR ((1)H, (13)C, (31)P, (77)Se, (125)Te) spectroscopy. These complexes crystallized out preferentially in sym-cis configuration. A low energy charge transfer transition has been identified from chalcogenolate centers to an empty pi* orbital of cyclometallated ligand in absorption spectroscopy in these complexes. The structures of [Pd(2)(mu-Cl)(mu-SMes)(C(10)H(6)NMe(2)-C, N)(2)] (1) and [Pd(2)(mu-SePh)(2)(C(10)H(6)NMe(2)-C, N)(2)] (3) have been established by single crystal X-ray diffraction analyses. In the former, the two palladium atoms are held together by chloro and thiolato bridges whereas in the latter, the two phenylselenolato ligands bridge two palladium atoms. The pyrolysis of [Pd(mu-TeMes)(C(10)H(6)NMe(2)-C, N)](2) (10) in a furnace gave Pd(7)Te(3) whereas thermolysis in TOPO afforded primarily PdTe(2). (C) 2008 Elsevier B. V. All rights reserved.
