TL;DR: In this paper, an optically active complex containing coordinated fluoride ion has been resolved for the first time, and the salt of the new complex ions, cis and trans [Co en2NO2F]+ were prepared.
Abstract: An optically active complex containing coordinated fluoride ion has been resolved for the first time. Salts of the new complex ions, cis and trans [Co en2NO2F]+ were prepared. Rates of aquation and racemization were measured for the complex [Co en2F2]+. It was of interest to find that the aquation of this complex is catalyzed by acid.

TL;DR: In this paper, the losses of optical activity calculated using the known rates of these individual steps agree reasonably with the measured losses of activity, which is consistent with the proposal that each chloroaqua → diaqua reaction occurs with complete retention of configuration in the range 1 < [H+] < 10-3M.
Abstract: Studies of the aquation reactions of the α and β [Co(trien)ClOH2]2+ isomers are complicated by subsequent isomerization and racemization of the respective diaqua products, especially in the α system. Assuming the consecutive reactions involved are Λ-α-chloroaqua → Λ-α-diaqua → racemic-β-diaqua and Λ-β1-chloroaqua → Λ-β-diaqua → racemic-β-diaqua the losses of optical activity calculated using the known rates of these individual steps agree reasonably with the measured losses of activity. The chloroaqua-diaqua equilibria lie substantially (c. 93 %) toward the diaqua products under all the reaction conditions studied. This is consistent with the proposal that each chloroaqua → diaqua reaction occurs with complete retention of configuration in the range 1 < [H+] < 10-3M.

TL;DR: In this paper, the activation volumes for spontaneous and Hg2+-assisted chloride release reactions from some [CoCl(N)5]2+ complexes have been estimated from the effect of pressure (5-150 MPa, I = 1.0 M HClO4) on the reaction rates.
