摘要

A new 2Fe2S complex [(2-C5H4N)N(μ-CH2S)2Fe2(CO)6] (1) related to the active site of [FeFe]-hydrogenase was obtained by treating (HS)2Fe2(CO)6 with (pyridin-2-ylazanediyl) dimethanol. Protonation occurred at the pyridine nitrogen atom when two equivalents of HBF4•OEt2 acid were added to the toluene solution of 1, leading to the formation of [(2-C5H4NH)N(μ- CH2S)2Fe2(CO)6]•BF4•OEt2 (1H+), whose molecular structure was further established by single- crystal X-ray analysis. Complex 1 crystallizes in the monoclinic system, space group P21/n with a = 7.728(3), b = 11.825(4), c = 17.888(6) Å, β = 92.968(5)º, while complex 1H+ crystallizes in the triclinic system, space group P with a = 7.672(4), b = 10.382(5), c = 16.480(10) Å, α = 106.575(13), β = 93.18(3), γ = 104.262(17)º.
