The experimental activation energies (E •) of dehydration of Cu(NH3)4(H20)SO 4, Cu(en)2(H20)X 2 (X = CI-, Br-), Cu(en)(H20)2SO 4, Cu(pY)2(H20)2SO4, CuCI2 9 2 H20 and M~CuCI 4 9 2 H20 (M ]-= NH 4, K, Rb) were obtained from their non-isothermal thermogravimetric curves using the Coats-Redfern method. These E ~ values were compared with known data on the structures of the Cu(ll) coordination polyhedra in the above complexes. No dependence of the E ~ values was found on either the central atom -released ligand bond length, or the number and lengths of the hydrogen bonds formed by the released water molecules. However, it was found that it is justified to seek some relationship between the E ~ values and the anisotropic temperature factors of the donor atoms of the ligands split off.
