The node-and-spacer approach is widely employed in crystal engineering to construct coordination polymers. It consists of self-assembly processes involving mononuclear cationic species and exo-dentate ligands. We enlarged this strategy using preformed homo- and heterometallic complexes as nodes. The presence of

The interaction between copper ions and gamma-L-glutamyl-L-cysteinyl-glycine [glutathione (GSH)] molecules may lead to the formation of the physiologically occurring Cu[I)-[GSH]2 and Cu(II)-GSSG complexes. Since glutathione depletion in neurons and aberrant copper metabolism have been implicated in several neurodegenerative disorders, we
