The influence of vacancies in the lead sublattice on the electronic spectrum, chemical bonding, and magnetic properties of the Pb1.5Fe(CN)6 phase is investigated. Analysis of the electronic spectrum shows that this compound is characterized by semi-conductor conductivity. It is demonstrated that the semiconductor gap is associated with the charge ordering of iron(III) ions. Полный текст |
