Graphical Abstract
Not so far away from me: Reductive cleavage of a disulfide ligand with CuI leads to the formation of a new mixed-valent CuIICuI complex (see picture). Combined X-ray and theoretical investigations highlight the presence of a striking Cu2S core containing a CuCu bond, and solution studies also indicate a high degree of delocalization.
