| Abstract: | The products of the cocondensation of iron atoms with benzene, at both 7 and 77 K, have been investigated by Mössbauer spectroscopy. On the basis of a benzene concentration study, it is concluded that iron forms two mononuclear bis-benzene complexes. By comparison of the Mössbauer parameters of these complexes to known systems, the two products are assigned to the 20 electron complex Fe(η6-C6H6)2 and the 18 electron complex Fe(η6-C6H6)(η4-C6H6). An Fe(C6H6) product is also formed at low benzene concentrations. |
