摘要：

The enthalpies of the reactions in 0.5 mole dm-3 (K)NO3 at 25°C between 1,7-diaza-4-thiaheptane (2,2-NSN) and 1,8-diaza-4-thiaoctane (2,3-NSN) and Cu2+ and Ni2+ ions have been determined by direct calorimetric titrations. δG values reported elsewhere have been used to calculate the corresponding δS values. It is found that in all the complexes the co-ordination of the sulphur atom is achieved, and that in the 1:1 complexes of Cu2+ and Ni2+ both ligands are acting as tridentates. Evidence is found for the incomplete coordination of the second ligand molecule in the CuL22+ complexes, whereas the NiL22+ complexes are six coordinate. © 1979.
