architecture to 1. The spectroscopic properties and the X-ray structures revealed that 2–4 are fully spin delocalized mixed valence (MV) of class-III type clusters. The structural parameters of the N2Cu2μ-S(R)}2 units of 3 and 4 closely resemble those of the MV binuclear CuA site. With the aid of UV–vis-NIR, EPR, and spectroelectrochemical studies, the electronic properties of these complexes have been described
