The thermal decomposition of the complexes M2ICu(SO4)2 · 6 H2O and M2Ni(SO4)2 · · 6 H2O (MI=NH4, K, Rb, Tl) containing the complex cation MII(H2O)62+ (MIl = =Cu, Ni) was studied. The values of the experimental activation energyE obtained for the dehydration reactions of both complex cations were found to be influenced in different ways by the outer-sphere cations present. It was therefore concluded that the activation energy of the decomposition of Cu(H2O)62+ depends on the degree of tetragonal distortion of this cation, which increases with the ionic radius of cation MI. TheΔH values of the studied reactions depend less on the structures of the coordination polyhedra. |
