摘要：

The volume of activation for aquation of Ru(NH3)5Cl2+ in acidic aqueous solution at 60 °C is -30 cm3 mol-1 at zero pressure but is markedly pressure dependent. The corresponding parameter for the reverse process is -20 cm3 mol-1, as measured directly and confirmed by densimetry. These and other data support accumulating evidence that an associative (A, or SN2 limiting) mechanism is quite general in simple substitution reactions of ruthenium(III) complexes in solution. © 1979, American Chemical Society.
