The reaction between (NBu4)[Pt(C6F5)2(acac)] and AgClO4 (1:1 molar ratio) in CH2Cl2 at room temperature gives the neutral tetranuclear complex [PtAg(C6F5)2(acac)]2 (1) in a good yield. The structure, which has been determined by single-crystal X-ray diffraction methods, shows two anionic fragments [Pt(C6F5)2(acac)]- linked by two Ag+ atoms, each silver center being bonded to a Pt atom of one fragment and to an oxygen atom of the acac ligand of the other fragment. Noteworthy structural features are the O-acac coordination of the silver atom (instead of the more usual Cγ coordination) and the unexpected presence of a dichloromethane molecule coordinated to the silver center. The reaction of 1 with tht (tht = SC4H8, tetrahydrothiophene) or PPh3 gives the dinuclear complexes [PtAg(C6F5)2(acac)-(L)] (L = tht (2), PPh3 (3)) by cleavage of the O-Ag bond; alternatively, complexes 2 and 3 can be one-pot synthesized by reaction of (NBu4)[Pt(C6F5)2(acac)] and O3ClOAgL (L = tht, PPh3). Their structural characterization points to the presence of donor-acceptor Pt→Ag bonds. Different behavior is observed in the reaction of (NBu4)[Pt(C6F5)2(acac)] with O3-ClOAuPPh3, giving the dinuclear complex [PtAu(μ-acac)(C6F5)2(PPh3)] (4) in which, as can be seen from its spectroscopic data, the gold atom is bonded to Cγ of the acac ligand.
