Abstract

Abstract The reaction of Fc(S2CNEt2)2 (Fc = Fe(η5-C5H4)2) with [Ag(OTf)(PPh3)] (OTf = trifluoromethanesulfonate) or [Au(OClO3)(PPh3)] in various molar ratios gives complexes of stoichiometry [Ag(PPh3){Fc(S2CNEt2)2}]OTf, [Ag(PPh3)2{Fc(S2CNEt2)2}]OTf, [Ag2(PPh3)2{Fc(S2 CNEt2)2}](ClO4)2or [Ag3(PPh3)3{Fc(S2CNEt2)2}](ClO4)3. Treatment of Fc(S2CNEt2)2 with Ag(OTf) gives the complex [Ag(OTf){Fc(S2CNEt2)2}], which can easily react with bidentate ligands such as 1,10-phenanthroline (phen), bis(diphenylthiophosphoryl)methane ((SPPh2)2CH2) or NaS2CNEt2 to afford the cationic complexes [Ag(phen){Fc(S2CNEt2)-}]OTf, [Ag{(SPPh2)2 CH2}{Fc(S2CNEt2)2}]OTf or the neutral [Ag(S2CNEt2){Fc(S2CNEt2)2}]. The crystal structure of [Ag(PPh3)2{Fc(S2CNEt2)2}]OTf reveals that silver coordinates to the dithiocarbamate sulfur atoms of two ferrocene ligands, thus forming a chain polymer.
