Although potassium, rubidium, and cesium uranyl nitrate have been characterized a long time ago, the crystal structure and properties of the homologous sodium compounds has not been reported yet. Na[UO 2 (NO 3 ) 3 ] crystallizes in a unique structure [Pearson code cP72, cubic, P2 1 3 , no. 198, Z = 4, a = 10.6324(14) Å, 938 unique reflections with I o > 2 σ ( I o ), R 1 = 0.0379, wR 2 = 0.0947, GooF = 1.092, T = 293 K]. The structure is characterized by an open framework built by interconnected helical chains formed by {UO 8 } and {NaO 6 } units. The vibrational and optical (UV/Vis absorption and luminescence) spectra match well with those of the higher alkali metal uranyl nitrates.
