Sa. Kostina et al., The interaction of N,N '-diethyl-4,4 '-bipyridinium cation with hexacyanoferrate(II) anions in aqueous solution, RUSS J IN C, 46(4), 2001, pp. 619-621
The interaction of the hexacyanoferrate ion with the N,N ' -diethyl-4,4 ' -
bipyridinium cation was studied spectrophotometrically. The background elec
trolyte cation concentration has an effect on the charge-transfer band posi
tions in the ion pairs. The stability constant and molar absorptivity of th
e ion pair and the rate constant of electron transfer between the ions were
calculated.
