Abstract
A uranium EXAFS study of the uranyl nitrate dimer [{UO2(mu-OH)(NO3)(2)}(2)] (2-) at 10 and 294 K is described. Low-temperature data readily reveal the presence of the second uranium atom in the complex as well as distinguishin g characteristics associated with the equatorial nitrate and bridging hydro xide groups. Observation and analysis of these critical components in EXAFS data collected at room temperature are much more difficult.
