• contrast, 2H-TCNPP is found to either form metal-organic networks or structures that, depending on the substrate, are stabilized by hydrogen bonding or dipolar coupling via its cyano groups [10][25][26]. This is similar to findings for other cyano-functionalized molecules [27][28][29][30]. The aim of this

• . The linker molecules retain an overall flat adsorption geometry. However, only networks with restricted local order were obtained, in marked contrast to previously employed, simpler polyphenylene-dicarbonitrile 1 linkers. Keywords: di(propiolonitrile) linker; lanthanides; metal–organic networks

• investigation of the self-assembly of the organic linker 2 on a Ag(111) surface revealed a densely packed, chevron monolayer exhibiting a Moiré pattern. In contrast, lanthanide coordination of the same ligand 2 with Gd atoms resulted in metal–organic networks with only local order. These latter results differ

• strongly from previous reports on 2D surface coordination of the related ligand terphenyl-4,4"-dicarbonitrile (1) linker by cerium or gadolinium atoms [20][21][42]. This indicates that the preference for the formation of extended metal–organic networks is not primarily a consequence of the geometrical

• intermolecular interactions between adjacent molecules due to hydrogen bonding [1][2][3][4], covalent bonding [5][6], or, in the case of metal organic networks, by metal–ligand interactions [1][7][8][9]. In these cases, the interactions between the adlayer and the substrate, or more specifically, the local
