N2 - Two series of iron-containing solid solutions Bi2Mg1-xFexNb2O9+δ and Bi2MgNb2-2xFe2xO9-δ of pyrochlore structure were obtained by the traditional solid phase synthesis method.

According to X-ray spectroscopy and magnetic susceptibility data, iron(III) atoms are distributed mainly in octahedral positions of niobium(V) and in a dominant amount are in the charge state of Fe(III) in the form of monomers and exchange-bonded clusters mainly with antiferromagnetic type of exchange.
