  摘要：

  A convenient preparation and full characterization, including a crystal structure, of green, crystalline [Co(NH3)(6)][Co(CO3)(3)] is reported. This salt can be treated at 0 degreesC with aqueous solutions of HClO4, HNO3 or CF3SO3H to give CO2(g), the corresponding insoluble salt of Co(NH3)(6)(3+) and aqueous Co(OH2)(6)(3+). This reaction provides ready access to solutions of Co(OHZ)(6)(3+) in a wide range of concentrations and acidities. (C) 2002 Elsevier Science B.V. All rights reserved.

  The reaction of Co(OH2)(6)(3+) with water has been studied in 1.0 M HClO4/LiClO4 at 25 degrees C. The reaction is biphasic, showing an initial increase and then decrease in absorbance at 325 and 605 nm. The rate of increase depends on (Co(OH2)(6)(3+)](2) and [H+](-2), while the decrease has an [H+](-1) dependence. The [H+](-2) and [H+](-1) dependence for the absorbance increase and decrease, respectively, may be accounted for by hydrolysis equilibria of Co(OH2)(6)(3+) and oligomeric species. The calculated values for k(1)K(1) and k(2)K(2) that fit the data are 3.5 x 10(-3) s(-1) and 3.2 x 10(-3) M s(-1), respectively, where K-1 is the hydrolysis constant of Co(OH2)(6)(3+), k(1) is the rate for the absorbance increase, K-2 represent the hydrolysis constant for the oligomer and k(2), the rate constants for the absorbance decrease.

  The acid dissociation constants, K h, of the hexaaquacobalt(III) and - manganese( III) ions are reported under conditions which minimize the problems of instability of these species at modest acidities ( pH 1 - 4). A rapid and convenient preparation of aqueous Co(III) has been used, and the latter has been reacted with aqueous Mn(II) to form aqueous Mn( III). The noncoordinating buffer H2PIPPS (1,4-bis(3-sulfopropyl)piperazine) has been used to react with H+ and provide some control of the pH. Spectrophotometric changes, after stopped-flow mixing for Co( III) and conventional mixing for Mn( III), were used to determine the K h values. The p K h values are as follows: Co( III), 3.10 +/- 0.07 (6.0 degrees C) and 2.92 +/- 0.04 (20.0 degrees C) in 1.0 M H+, Na+, ClO4-; Mn(III), 0.22 +/- 0.04 (7.6 degrees C) and 0.08 +/- 0.04 (20.0 degrees C) in similar to 4 M H+, Mn2+, ClO4-. Global fits of the data for each metal have been used to estimate the Delta H degrees and Delta S degrees values for K-h. It is suggested that the unusually high acidity of Mn(OH2) (3+)(6) may be due to a Jahn-Teller distortion effect.
