摘要：

Reaction of lithium ferrocenylacetylide (LiFcA) with [CO3(dpa)(4)(NCCH3)(2)](PF6)(2) (dpa = 2,2'-dipyridylamide) in acetonitrile solution yields the bisferrocenylacetylide EMAC (extended metal atom chain) Co-3(dpa)(4)(FcA)(2) in good yield and excellent purity. The crystal structure features a distinctly unsymmetrical tricobalt chain with a Co-Co bond distance of 2.3091(8) Angstrom and a longer Co...Co separation of 2.5208(9) Angstrom. Cyclic and differential pulse voltammetry show that the two Fe-2divided by13divided by oxidations occur nearly simultaneously, with a DeltaE(1/2) of 71 mV.
