%X Studies of the aquation reactions of the &#945; and &#946; [Co(trien)ClOH2]2+ isomers are complicated by subsequent isomerization and racemization of the respective diaqua products, especially in the &#945; system. Assuming the consecutive reactions involved are                      &#923;-&#945;-chloroaqua &#8594; &#923;-&#945;-diaqua &#8594; racemic-&#946;-diaqua  and                      &#923;-&#946;1-chloroaqua &#8594; &#923;-&#946;-diaqua &#8594; racemic-&#946;-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 &#8594; diaqua reaction occurs with complete retention of configuration in the range 1 < [H+] < 10-3M.
