It is demonstrated that the identity of the ligand labilized from the ligandfield excited states of [Rh(NH3)5Cl]2+ is a function of the solvent medium, with Cl– substitution predominating in water and formamide solutions but NH3 substitution predominating in dimethylformamide, methanol, and dimethyl sulphoxide solutions.

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
