•We observed valence tautomerism in copper complex.•Antiferromagnetic spin interaction at low temperature was assumed.•The role of ligands was revealed. Electronic structure of copper complexes with redox-active ligands was studied by XPS. The temperature dependence of the redistribution of electron...
