Description
A reversible colour change from lemon-yellow to orange was observed for polycrystalline UO2(hfa)2 NH3 at 1000C (hfa = (1,1,1,5,5,5-hexafluoro-2,4-pentanedione)). The changes in the X-ray powder pattern between -1960 and 1300C were followed with a Guinier-Simon focussing camera. The colour change was not due to an α - β type structural transition as found earlier in α and β-UO2(hfa)2 tmp (tmp = trimethyl phosphate), but was considered to be due to changes in the hydrogen bonding of the ammonia molecules.
