Alkali Counterion-Dependent Crystallization of Uranium(IV)-Chloro Structural Units.

ABSTRACT: The synthesis, structural characterization, and spectroscopic properties of five tetravalent uranium (U) phases including Li₆[U₄(μ₃-O)₂Cl₁₈(H₂O)₂]·10H₂O (1), [U(H₂O)₄Cl₄] (2), [U(H₂O)₄Cl₄]·KCl (3), Rb₂UCl₆ (4), and Cs₂UCl₆ (5) are reported. Notably, a change in the U⁴⁺ solid-state structural unit was observed based on the identity of the alkali counterion used in the synthesis. Li¹⁺ yielded a tetranuclear oxo-bridged cluster, [U₄(μ₃-O)₂Cl₁₈(H₂O)₂]^6-, Na¹⁺
