• Reaction of UO<SUB>2</SUB>F<SUB>2</SUB> with UF<SUB>5</SUB> at 400 °C under UF<SUB>6</SUB>-pressure of 3 atm followed by evaporation of excess UF<SUB>5</SUB> has yielded a greenish white residue. Its X-ray diffraction pattern and infrared spectrum are sufficiently unique to establish that this material is a true compound. Its chemical formula has been shown to be U<SUB>2</SUB>O<SUB>2</SUB>F<SUB>7</SUB>, on the grounds of chemical analysis and thermal decomposition. The oxygen content was determined directly by means of <SUP>18</SUP>O isotopic dilution method based on the combustion of the samples with BrF<SUB>5</SUB>.
