High-temperature oxide melt solution calorimetry and Rietveld refinements of powder X-ray diffraction data were used to investigate the structure (Fd3m, Z=8) and energetics of a series of RE[2]Ti[2]O[7] (RE=Sm-Lu) compounds with the pyrochlore structure as well as La[2]Ti[2]O[7] with a layered perovskite-type structure.
