β¦ Synopsis
A simple extended Hiickel type molecular orbital model is proposed for mixed-valence bioctahedral clusters. The model allows the study of the delocalisation of the excess electron in these systems as a function of the arrangement of octahedral units, metal-metal distances and electronic configurations. Fe(ll)-Fe(lll) clusters with oxygen ligands are considered as examples, it is shown that the model provides information about the electronic structure of mixed-valence clusters which cannot be obtained from phenomenologicai vibronic theories.
