two pyridine nitrogens, one pyrimidine nitrogen and two chloride anions. Two DPP ligands act as tridentate donors and coordinate to two copper ions forming a large metallocyclic ring. In II DPP still acts as a tridentate ligand, but coordinates to two Cu(II) ions, linking the metal centers in a polymeric chain. Each copper ion has a square pyramidal geometry with three nitrogen donors from the DPP
