Abstract

Phases of general formula M2FeV3O11, where M=Mg, Co, Ni and Zn as well as the orthorhombic modification of FeNb11O29, have been investigated by the help of IR and Mössbauer spectroscopy. It was found that the isostructural compounds Co2FeV3O11, Mg2FeV3O11, Zn2FeV3O11, as well as Ni2FeV3O11 with a different structure have one single and almost identical chemical environment for iron(III). The large Mössbauer quadrupole splitting measured suggests that iron(III) is located in a highly distorted octahedron. The IR spectra of three isostructural M2FeV3O11 compounds are similar but differ from that of Ni2FeV3O11. The Mössbauer spectrum of orthorhombic FeNb11O29 has been fitted with two doublets, their hyperfine parameters indicating iron in distorted octahedral environment.
