On the relationship between the structures of CuII complexes and their chemical transformations. XV: Thermal decomposition of compounds [Cu(LL)(H2O)2](SO4) and accompanying structural changes

In the mutually isomorphous compounds [Cu(LL)(H 2 O) 2 ](SO 4 ), (LL=ethylenediamine (I), 2,2'-dipyridine (II) and 1, 10-phenanthroline (III)) are the water molecules cis-bonded to the central atom. The activation energies and preexponential factors gained for dehydration reactions of studied complexes do not differ very much from those, gained for dehydration of compounds with trans-bonded water molecules. The higher values of activation energy and preexponential factor were gained for compound 1, the lower values for compound III.
