Significats de dication en anglès

The dication lies across a crystallographic inversion center.

Ready generation of radical cations was supported by cyclic voltammetry measurements, revealing stepwise formation of radical cation and dication species in solution.

Spectroscopic studies indicated that these radical cations and dications have good stability.

In substitution reactions at the phosphorus atom the triflyloxy moiety serves as a leaving group and enables the synthesis of rare examples of pseudo-halophosphonium dications.
