This could be due to intramolecular electron transfer via valence tautomerism between electroactive ligand and metal ion [23-26] causing fast disproportionation of Cu(I) complex to give Cu(II) or some rearrangement within complex so as to give a more stabilized species.

In addition to magnets and nanomagnets, we have reported several tunable paramagnetic mononuclear complexes showing spin crossover, valence tautomerism, and changes in orbital angular momentum.
