The reaction of tetradentate or bidentate Fe(II) salicylaldimine compounds with aryl azides in methylene chloride results in elimination of nitrogen and formation of Fe(III) μ-organoimido-bridged complexes [Fe(Lig)]2NR. Studies of the magnetic susceptibilities of the compounds to 4.2 K show that they possess antiferromagnetic coupling similar to that of the analogous μ-oxo compounds. Mo?ssbauer spectra indicate Fe(III) centers with S = 5/2 spin. Crystal data for (μ-p-tolylimido)bis[(N,N′-ethane-1,2-diylbis(salicylaldiminato)) iron(III)] ([Fe(salen)]2N(Tol)) (C39H35Fe2N5O4): triclinic, P1, a = 13.331 (4) A?, b = 12.123 (5) A?, c = 11.002 (5) A?, α = 101.88 (2)°, β = 96.64 (3)°, γ = 97.53 (4)°, V = 1706 (1) A?3, Z = 2. The Fe-(μ-N)-Fe angle is 129.6 (6)°.
