The new uranyl polychalcogenide compounds Cs4(UO2)(S2)3 and Na4(UO2)(S2)3 · Na2S3 were synthesized in molten polysulfide salts in the temperature range of 350-400°C and were characterized with single crystal X-ray crystallography. Both compounds contain the mononuclear anionic complex [(UO2)(S2)3]4-. The uranyl cation is coordinated to three chelating (S2)2- species such that the midpoints of each disulfide define the equatorial positions of a trigonal bipyramidal coordination for U.
