Cobalt Complexes with As4 LigandsThe reaction of [Cp*Co(μ-CO)]2(Co = Co) (1) with As4 in boiling toluene gives the cobalt complexes [Cp*Co(CO)(η1:1-As4)] (2), [{Cp*Co(CO)}2(μ-η1:1:1:1-As4)] (3), exo,endo-[Cp*Co(μ-η4:1:1-As4)Co(CO)Cp*] (4a, b), and [Cp*Co(μ-η2:2-As2)]2 (5), Cp* = C5Me5. 2,3, and 4b have been characterized by X-ray structure analyses. With respect to the mechanism of this reaction the successive cleavage of two, three, and four As-As bonds of yellow arsenic, As4, has been proved.
