摘要：

Reduction of [FeCl2(depe)(2)] (depe = Et2PCH2CH2PEt2) by sodium-naphthalene under nitrogen gave a dinitrogen complex of iron(o), [Fe(N-2)(depe)(2)] 1, in 72% yield. The crystal structure of 1 shows that the dinitrogen ligand bonds in an end-on fashion in a trigonal-bipyramidal geometry. Protonolysis of 1 by HCl gave trans-[FeH(Cl)(depe)(2)] with quantitative evolution of molecular nitrogen and then [FeCl2(depe)(2)] with molecular hydrogen. The dinitrogen ligand in 1 can be replaced by small molecules such as CO, CS2 or H-2 to give [Fe(CO)(depe)(2)], [Fe(CS2)(depe)(2)] and cis-[FeH2(depe)(2)] respectively. The molecular structure of [Fe(CO)(depe)(2)] has been established by X-ray analysis.
