Abstract

Three different phosphate structures, α-K₂Mo₂P₂O₁₁, β-K₂Mo₂P₂O₁₁ and CdMoPO₆, in which molybdenum(V) octahedra are assembled in different ways, have been studied by vibrational spectroscopy techniques. A correlation is given between crystal structure and infrared and Raman band behaviour which allows identification of vibrational modes sensitive to a particular configuration of molybdenum species. This represents a powerful tool for structure characterisation when amorphous or single layer supported phases are under study.
