Encapsulation of the Na + ions of the [Na 2 (P 4 R 4 )] ion triple with a R , R or S , S configuration at the inner phosphorus atoms by cryptands has enabled cation‐separated dianions to be obtained in a crystalline form. Fragmentation of the {Na([2.2.2]cryptand)} 2 (P 4 R 4 ) into radical anions (P 2 R 2 ) .− occurs in solution (see scheme), as determined by EPR spectroscopy.
