by performing various test reactions. To validate these mechanisms, DFT calculations have been carried out. Interestingly, the reactions of the mixture of LSeX2/L′SeX2/L′′SeX2 and L′Se0/L′Se0/L′′Se0 with metal halides (FeCl3, ZnX2; X = Cl, Br, I; CdI2, HgI2, PdCl2, and PtCl2) produced dicationic diselenides, 7–12, 15, 17 and [L2Se22+]Y [Y = ZnI4}2− (19), CdI4}2− (22), HgI4}2− (25), PdCl4}2− (26)
