摘要:
AbstractAgClO4 reacts with bidentate ligands 2‐(methylthio)pyridine (SMepy) or complexes PPN[Au(Spy)2] [PPN = N(PPh3)2, HSpy = pyridine‐2(1H)‐thione) or PPN[Au(Sbz)2] (HSbz = benzoxazole‐2(3H)‐thione), themselves acting as ligands, to give dinuclear complexes [Ag2(μ‐SMepy)2](ClO4)2 (1), [AgAu(μ‐Spy)2] (2), or [AgAu(μ‐Sbz)2] (3), respectively. By treating 1 with [AuCl(tht)] (tht = tetrahydrothiophene), [Au(SMepy)(tht)]ClO4 (4) is obtained which, in turn, reacts with SMepy to give [Au(SMepy)2]ClO4 (5). Similarly, [PdCl2(NCPh)2] reacts with SMepy in 1:1 molar ratio to give [Pd2Cl2(μ‐Cl)2(SMepy)2] (6) which reacts with SMepy in 1:2 molar ratio to give [PdCl2(SMepy)2] (7). On the other hand, HSpy reacts with Ag2CO3 to give [Ag2(μ‐Spy)2] (8), and (SMepyH)ClO4 reacts with [Au(acac)PPh3] (acacH = acetyl‐acetone) to give [Au(SMepy)PPh3]ClO4 (9).
