Abstract

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.
