Surface‐Assisted Assembly of 2D Metal–Organic Networks That Exhibit Unusual Threefold Coordination Symmetry

Independent symmetries characterize the evolving network and the metal surface on which the network forms in the surface-assisted assembly of ligands and metal centers to 2D honeycomb networks comprising threefold coordination motifs (see picture, Co purple, N green). This type of coordination, which is rarely encountered in 3D metal–organic frameworks, is promoted by the strict confinement of a 2D environment.
