Notes:
Nd2O2(O2) has been formed at very high oxygen pressures in an unsuccessful attempt to prepare neodymium(IV) dioxide, Nd4+ O2, and contains oxide (O2-) and peroxide (O22-) ions. The structure of Nd2O2(O2) closely resembles that of CaF2 and its full vibrational spectra could be interpreted in terms of this structure. Although Nd2O2(O2) has a monclinic structure, its vibrational spectra are not in agreement with the monoclinic B-type phase of the lanthanide(III) sesquioxides, and it is shown why this is so. Many of the Nd—O vibrational modes in Nd2O2(O2) agree, however, with those observed in the trigonal A-type Nd2O3, and the ν (O—O) stretching and Nd—O—O bending modes could be clearly identified.
