The kinetics of the reactions [R(NH3)5X]2++ OH–→[R(NH3)5OH]2++ X–(X = Cl, Br, I) have been studied over a range of temperatures under conditions which allow the calculation of second-order rate constants at zero ionic strength.

Photolyses of rhodium(III) complexes, Rh(NH3)5X2+ (X = Cl− and Br−), under intense magneticfields, e.g. λexcit = 360 nm and H = 24 kG, have been investigated. The magneticfield quenches the photoaquation of the ammonia and enhances the photoaquation of the acido ligand, X = Cl− or Br− by 10% for H = 24 kG. The implication of two different precursors in the formation of the photoproducts is discussed

The second-order rate constants for the mercury(II)-induced aquation of [Rh(NH3)5X]2+ cations (where X = Cl or Br) have been measured in aqueous solution over a range of temperatures. The results are interpreted in terms of the formation of an activated complex RhXHg, which yields the aquopentamminerhodium(III) product by a unimolecular aquation with HgX+ as the leaving group. The effect of changing
