The iron(0) dinitrogen complexes [Fe(N 2 )(PP 3 R )] (PP 3 R = P(CH 2 CH 2 PR 2 ) 3 , R = Ph, i Pr, Cy) were synthesized by reduction of the precursor chloro complexes with potassium graphite. On reaction with triflic acid, [Fe(N 2 )(PP 3 R )] complexes afforded ammonia and hydrazine in yields of up to 23 and 16 % respectively. The complex [Fe(N 2 )(PP 3 Ph )] which has only been previously synthesized in situ, has now been isolated and fully characterized by 15 N NMR spectroscopy and by X‐ray crystallography.
