Abstract

Two Fe-Ta containing sulfido complexes were prepared by the reaction of the metal halide salts with bis-trimethylsilylsulfide in the presence of PMe 3. The complexes demonstrate that coordination chemistry with iron sulfides can give access to a range of heterometallic complexes. In [Cl(Me 3P)Ta(μ2-S)23-S) Fe(PMe 3)2]2 the two [Cl(Me3P)Ta] units are arranged around one central Fe22-S)2 unit. In [(Me3P)4(MeCN)2FeII] 2+[(Me3P)2TaIVFe3 II3-S)4Br4]2- a [TaFe3S4]2+ cuboidal arrangement was observed. The complex salt forms a polymeric structure in the solid-state with weak H-bonds between the ions. The [(Me3P)2Ta IVFe3II3-S)4Br 4]2- ion was characterised by magnetic measurements showing strong antiferromagnetic interactions between the metal centres.
