Resumo

The low-valence cobalt cluster [Co7(μ4-S)3(μ3-S)3(PPh3)6Br] (1) was isolated from the reaction of Co(PPh3)3Br with Na2edt in ethylene chloride. The skeleton [Co7S6]+ of 1 can be represented as a monocapped-prismane formed by the addition of the capping atom cobalt to the prismane [Co6S6] as shown by X-ray single-crystal structure analysis. In this reaction the S2− ion is derived from the edt2− ion through cleavage of the CS bond, and incorporated into the building process.
