摘要:
The rate of Hg2+-assisted chloride release from several mer-[CrCl(diamine)(triamine)](2+) complexes has been measured as a function of pressure, Hg2+ concentration and temperature. The calculated activation volumes are independent of [Hg2+] and temperature and kinetic parameters 10(4) k(Hg) (25 degrees C) (M(-1) s(-1)), Delta H double dagger (kJ mol(-1)), Delta S double dagger (J K-1 mol(-1)), Delta V double dagger (cc mol(-1)) are: (en)(dpt): 6.44, 75.5, -53, -5.0; (ibn)(dpt): 5.81, 89.5, -6, -0.03; (Me(2)tn)(dpt): 22.2, 84.9, -11, -0.5; (tn)(dpt): 29.1, 87, -1, +0.3; (en)(2,3-tri): 1.94, 87.0, -24, -5.7; (en)(Medpt): 0.417, 94.6, -11, -0.8; (tn)(Medpt): 9.14, 98.3, +26, +1.8.
