Reactivity studies on [Cp'Fe(μ-I)]₂: nitrido-, sulfido- and diselenide iron complexes derived from pseudohalide activation.

ABSTRACT: The iron half-sandwich [Cp'Fe(μ-I)]₂ (Cp' = 1,2,4-(Me₃C)₃C₅H₂, 1) reacts with the pseudohalides NCO^-, SCN^-, SeCN^- and N₃^- to give [Cp'Fe(μ-NCO)]₂ (2), [Cp'Fe(μ-S)]₂ (3), [Cp'Fe(μ-Se₂)]₂ (4) and [Cp'Fe(μ-N)]₂ (5), respectively. Various spectroscopic techniques including X-ray diffraction, solid-state magnetic susceptibility studies and ⁵⁷Fe Mössbauer spectroscopy were employed in the characterization of these species. Mössbauer spectroscopy shows a decreasing isomer shift with increasing formal oxidation state, ranging from Fe(ii) to Fe(iv), in complexes 1 to 5. The sul
