Abstract

The thioarsine, AsMe2(SPh), reacts thermally with [Fe(CO)5] to give the new bimetallic butterfly complex, [Fe2(CO)6(μ-AsMe2)(μ-SPh)] (1). Similarly, thermolysis of the thioarsine AsPh2(SPh) with [Fe2Cp2(CO)4] and [Mn2(CO)10] affords, respectively [Fe2Cp2(CO)2(μ-AsPh2)(μ-SPh)] (2) and [Mn2(CO)8(μ-AsPh2)(μ-SPh)] (3). At room temperature, AsPh2(SPh) reacts rapidly with [Co2(CO)8] to yield the trimetallic product, [Co33-S)(μ-AsPh2)(CO) 6AsPh3] (4). The crystal structures of these four products have been determined by X-ray crystallography. Arsenic-sulfur bond cleavage is a feature of all these reactions; concomitant arsenic-carbon bond formation is observed in the production of complex 4.
