Anions as Electron Donors in Charge-Transfer Salts

Isolation and Spectral Characterization of Charge-Transfer Salts of Carbonylmetallates 

Analogously, when a colorless aqueous solution of quinolinium chloride (Q+ Cl ) is mixed with an almost colorless aqueous solution of Na+ V(CO)6 , the well-formed dark green crystals of the vanadate salt precipitate immediately. In each case, the spontaneous separation of the highly colored salts is made even more dramatic by the absence of color in the aqueous mother liquors throughout the course of precipitation. 

According to Mulliken charge-transfer theory (7), the separation of AhvCT = 0.61 eV for the two series represents the constant difference in the donor properties (ionization potential) of Co(CO)4- and I- in salt pairs with the same acceptor cation. The latter is a corollary of the Mulliken
