Abstract

The reaction of Ce with the basic polychalcophosphate flux Rb10P4Se25 yielded the quaternary selenophosphate compound Rb9Ce(PSe4)4. The discrete [Ce(PSe4)4]9- anion possesses the highest charge observed in a monometallic complex. The Ce3+ center is chelated by four bidentate [PSe4]3- ligands so it achieves a dodecahedral coordination geometry, and the complex belongs to the dodecahedral sub-class Id (D2d-4̄2m), according to the Hoard and Silverton notation. The UV-Vis, optical, IR spectroscopic and magnetism data for the compound are reported.
