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)₂(μ₃-S) Fe(PMe ₃)₂]₂ the two [Cl(Me₃P)Ta] units are arranged around one central Fe₂(μ₂-S)₂ unit. In [(Me₃P)₄(MeCN)₂Fe^II] ²⁺[(Me₃P)₂Ta^IVFe₃ ^II(μ₃-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 ^IVFe₃^II(μ₃-S)₄Br ₄]^2- ion was characterised by magnetic measurements showing strong antiferromagnetic interactions between the metal centres.
