Surface safari : 9,10‐Anthracenedicarbonitrile (DCA) molecules adsorbed on a Cu(111) surface can be titrated by gradual annealing of the substrate to form trigonal planar Cu(DCA) 3 complexes and, ultimately, a hexagonal network (see picture) with a Cu 2 (DCA) 3 stoichiometry. As a result of charge donation from the substrate, the coordinated Cu adatom remains electrically neutral despite donating approximately 1/3 charge to each CuN bond.
