Abstract

The treatment of FcLi2·TMDA with pyS–Spy (py = 2-pyridyl) leads to the new ferrocene derivative Fc(Spy)21. The reaction of 1 with gold(I) or gold(III) complexes gives heterometallic complexes of the type [ {Au(C6F5)}2{Fc(Spy)2}], [{Au(PPh3)}2{Fc(Spy)2}](OTf)2 or [{Au(C6F5)3}2{Fc(Spy)2}] where the coordination of the gold centres takes place through the nitrogen atoms as evidenced by two crystal structure determinations. Complex 1 also reacts with silver complexes to afford derivatives such as [Ag(OTf){Fc(Spy)2}], [Ag(PPh3){Fc(Spy)2}]OTf, [{Ag(PPh3)}2{Fc(Spy)2}](OTf)2 or [Ag2{Fc(Spy)2}3](OTf)2. Substitution of the triflate ligand in [Ag(OTf){Fc(Spy)2}] by bidentate ligands such as phen or SdppmS gives [Ag(phen){Fc(Spy)2}]OTf or [Ag(SdppmS){Fc(Spy)2}]OTf. The silver complex [Ag2{Fc(Spy)2}3](OTf)2 has also been characterised by X-ray diffraction showing three 1,1′-bis(2-pyridylthio)ferrocene ligands bridging two silver atoms.
