The compound Na8[(UO2)(S2)3]2(CH3OH)15(H2O) was synthesized at room temperature in an oxygen-free environment and was characterized IR and UV-vis spectra. Single crystal X-ray diffraction reveals this uranyl disulfide monomer contains a rare example of the [(UO2)(S2)3] complex in which a uranyl ion is coordinated by three disulfide groups that are each bidentate to the uranyl ion. Comparison has been made between the possible linkage of these units to form nano-scale cage clusters analogous and those formed from uranyl peroxo polyhedra, which might support the hypothesis of the synthesis of cage nanoclusters based on uranyl sulfide.
