资源简介:
Reaction of lithium ferrocenylacetylide (LiFcA) with [Co3(dpa)4(NCCH3)2](PF6)2 (dpa = 2,2‘-dipyridylamide) in acetonitrile solution yields the bis-ferrocenylacetylide EMAC (extended metal atom chain) Co3(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) Å and a longer Co···Co separation of 2.5208(9) Å. Cyclic and differential pulse voltammetry show that the two Fe2+/3+ oxidations occur nearly simultaneously, with a ΔE1/2 of 71 mV.
