Three different phosphate structures, alpha -K(2)Mo(2)P(2)O(11), beta -K(2)Mo(2)P(2)O(11) and CdMoPO(6), 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.

Abstract
Three different phosphate structures, alpha -K(2)Mo(2)P(2)O(11), beta -K(2)Mo(2)P(2)O(11) and CdMoPO(6), 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.
