Isolation of a zerovalent iron dinitrogen complex with 1,2-bis(diethylphosphino)ethane ligands

Abstract
A zerovalent iron dinitrogen complex [Fe(N2)(depe)2] having 1,2-bis(diethylphosphino)ethane ligands has been prepared by reduction of [FeCl2(depe)2] with sodium–naphthalene in tetrahydrofuran under nitrogen at room temperature.
