Adducts of co-ordination compounds. Part X. Solvates and adducts of dihalogenotetrapyridinerhodium(III) salts
Abstract
The cations trans-[M(py)4X2]+, where M = Rh or Ir and X = Cl or Br, readily form stable salts with uncommon anions, such as polyhalides. This stabilisation in solids is illustrated by the new salts [M(py)4Cl2](Cl3)[M = Rh or Ir] and [Rh(py)4Cl2](Br2Cl) and some solvates, e.g., [Rh(py)4Cl2](ClO4)MeNO2.
