  Oxidative access to flexible {Pt2(μ-SAr)2} square motifs from platinum thiolato complexes with chelating diphosphine

  摘要：

  Platinum(II) aryl thiolate complexes formulated as (P2)Pt(SAr)(2) are prepared from the chelating bis(diphenylphosphino) dimethyltetrathiafulvalene (P2), with aryl thiolate ligands (SAr), such as benzene-thiolate (BT) and 3,5-dimethylbenzenethiolate (DMBT). The structurally characterized neutral (P2) Pt(SAr)(2) complexes afford, upon oxidation with TCNQF(4), dicationic bimetallic Pt(II) complexes formulated as [(P2)Pt(mu-SAr)(2)Pt(P-2)](2+), characterized by a flexible {Pt-2(mu-SAr)(2)} square motif. The magnetic properties of the TCNQF(4)(-) salts of these bimetallic Pt(II) complexes are determined from susceptibility measurements and a tentative rationale for the formation of such {Pt-2(mu-SAr)(2)} square complexes are provided, based on an original oxidative dimerization process.

  Unexpected Reactivity of PdCl₂ and PtCl₂ Complexes of the Unsaturated Diphosphine o-Me₂TTF(PPh₂)₂ toward Chloride Abstraction with Thallium Triflate

  摘要：

  Attempted thallium triflate abstraction of chloride anions from the MCl2 complexes of the unsaturated chelating diphosphines o-dimethyl-bis(diphenylphosphino)tetrathiafulvalene (P2) (M = Pd, Pt) and cis-1,2-bis(diphenylphosphino)ethylene (dppen) (M = Pd) affords, surprisingly, a TI(OTf) adduct in the case of (P2)PdCl2 and (P2)PtCl2, with no chloride abstraction, and a dicationic bis(palladium) bis(triflate) salt in the case of (cis-dppen)PdCl2, in which only one Cl anion was removed. The crystal structures of these complexes were determined by X-ray analysis, which established the formulations (P2)MCl2.TI(OTf) (M = Pd, Pt) and [(dppen)PdCl](2)(OTf)(2), respectively. These compounds can be seen as possible intermediates in the general chloride abstraction process between (P-P)MCl2 (M = Pd, Pt) and thallium triflate.
