Abstract

A uranium EXAFS study of the uranyl nitrate dimer [{UO₂(μ-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 distinguishing characteristics associated with the equatorial nitrate and bridging hydroxide groups. Observation and analysis of these critical components in EXAFS data collected at room temperature are much more difficult.
