“…The low temperature (LT) crystalline form of Li3P04 was produced by slowly adding phosphoric acid to a boiling solution of LiOH and H@. [23] Crystals immediately precipitated as the phosphoric acid was added. The boiling mixture of crystals and water was stirred for -5 minutes and then oven-dried overnight at 125"C. Both powder x-ray diffraction (XRD) and31P MAS NMR were used to confirm the phase purity of these crystalline compounds.…”

The electronic structures of different phosphates were studied by using the DV-Xa cluster molecular orbital method. Experimental data on crystal structures from x-ray difiaction measurements were used to set up realistic model clusters. Theoretical XPS valence band spectra obtained from the DV-Xa calculations were compared to our high-resolution XPS measurements on polycrystalline powder Li,PO., , Na,PO, , Na,P,O, and (NaPO,), samples. These new measurements made possible a more rigorous test of the theoretical approach and more reliable shape analysis than the previous set of data obtained by non-monochromatized measurements combined with the resolution enhancement technique. Systematic study of different clusters showed that the cations around the PO4 cluster and the distortion of the PO., tetrahedra due to the anisotropic crystal forces play only a minor role and their influence on the valence band spectra was found to he negligible. In the case of polyphosphates, considerable changes were found in the valence band spectra as a consequence of small changes in the bond angle of the P-0-P bridges. Our results, based on cluster parameters specific to the anhydrous crystals, are in good agreement with the experiments.

“…We then searched the structural literature (2Q) for compounds that exhibit structures in one of these space groups with three different atoms in a 3:1:4 stoichiometry (assuming that the three oxygens and one nitrogen are disordered). We found only one example, the low temperature form of Li 3 PO 4 which crystallizes in the acentric space group Pmn2 1 (21).…”
