Both the electrostatic theory of binary complex formation and statistical arguments clearly indicate that, in the case of a given multivalent hydrated metal ion, more coordination positions will be available for the first ligand than for the ML second one. Hence, the order of stability K M ML >K ML2 ...

... When the monomeric species change into dimeric species having axial symmetry and identical sites, the ‘g’ values also change due to the change in symmetry [27]. The spectra have asymmetric bands with two ‘g’ values g║ and g┴. The trend g║>g┴>g (2.002), indicates that unpaired electron lies predomina ...
