The action of MeSO3CF3 on [Fe2(cp)2(CO)2(μ-CO){μ-C(CN)SMe}] 1 (cp = η5-C5H5) yields [Fe2(cp)2(CO)2(μ-CO){μ-C(CN)SMe 2}][SO3CF3] 2. The sulphonium cation is also obtained, trapped in the unusual triflate complex Fe(OSO2CF3)4{Fe2(cp) 2(CO)2(μ-CO)[μ-C(CN)SMe2}2] 3, by treating the thiolcarbamate [Fe2(cp)2(CO) 2(μ-CO){μ-C(CN)N(Me)C(O)SMe}] 4 with MeSO3CF3. The X-ray crystal structure of 3 shows the iron(II) centre co-ordinated by four O-bonded triflate anions and by two, mutually trans-disposed, N-co-ordinated organometallic cations in an octahedral geometry.

Abstract
The action of MeSO3CF3 on [Fe2(cp)2(CO)2(μ-CO){μ-C(CN)SMe}] 1 (cp = η5-C5H5) yields [Fe2(cp)2(CO)2(μ-CO){μ-C(CN)SMe 2}][SO3CF3] 2. The sulphonium cation is also obtained, trapped in the unusual triflate complex Fe(OSO2CF3)4{Fe2(cp) 2(CO)2(μ-CO)[μ-C(CN)SMe2}2] 3, by treating the thiolcarbamate [Fe2(cp)2(CO) 2(μ-CO){μ-C(CN)N(Me)C(O)SMe}] 4 with MeSO3CF3. The X-ray crystal structure of 3 shows the iron(II) centre co-ordinated by four O-bonded triflate anions and by two, mutually trans-disposed, N-co-ordinated organometallic cations in an octahedral geometry.File in questo prodotto:
