<p> The symmetries and unit cell dimensions of crystals of Na4P2O7, δ-Ba2P2O7 and H4P2O7 have been determined by X-ray diffraction methods. Changes in symmetry and unit cell dimensions of Na4P2O7 as a function of temperature have been described and a model has been proposed describing the statistics of these changes. The existence of disorder in the crystal structure of δ-Ba2P2O7 has been established and the unit cell dimensions of a previously unreported low temperature form are reported.</p> / Thesis / Master of Science (MSc)
