Abstract

Mössbauer spectra of [Fe(C₆Cl₅)₂L₂], L = PEt₃ and PEt₂Ph have been recorded at different temperatures. The low δ values show a high degree of covalency in the ironligand bonds, and the large Δ values are consistent with a planar geometry. The Mössbauer emission spectra of some [⁵⁷Co(C₆Cl₅)₂L₂] (L = PEt₃, PEt₂Ph or PEtPh₂) show no Mössbauer effect, suggesting the formation of a new iron specimen during the ⁵⁷Co(EC)⁵⁷Fe reaction, with an extremely small f-factor. [Fe(C₆Cl₅)₂L₂] compounds have been prepared either from the reaction of C₆Cl₅MgCl and [FeCl₂L₂] or by the addition of the phosphine to a solution of the 'Fe(C₆Cl₅)₂' complex. The stability of these complexes has been studied in different solvents and in the presence of bromine.
