Heterobinulear complexes of general formula 14-21 have been prepared by treating the anionic platinum derivatives with (molar ratio 1:1) in dichloromethane.The anionic <(C6F5)4PtAgL> (L = OEt2, PPh3 or tht) 22-24 and 25 have been obtained from the corresponding 2 and (molar ratio 1:1) in CH2Cl2-diethyl ether.The reaction between and renders Ag(C6F5) and cis-.The salts 2 and 24> react with yielding and , respectively.The reactions between 2 and or (molar ratio 1:2) render in the first case complex 24 while in the second an unstable material which evolves to <(Ph3P)(C6F5)3PtAg(PPh3)> 27 is obtained. The reaction between 2 (X = F or Cl) and or ClO4 have also been studied.The structures of <(tht)(C6Cl5)(C6F5)2PtAg(PPh3)> 14, <(C6F5)4PtAg(tht)> 24 and 25 have been established by single-crystal X-ray diffraction studies.The complexes contain a strong Pt->Ag bond <2.650(2), 14; 2.641(1), 24; and 2.692(2) Angstroem, 25> unsupported by covalent bridges, and short contacts between the o-F or o-Cl atoms of the C6X5 (X = F or Cl) groups and the Ag atom are present.The relative strength of such contacts is discussed.Methods for the synthesis of mixed pentachloro-pentafluorophenyl starting complexes 1-13 have been investigated.
