The formation of extended two-dimensional metal-organic coordination networks (2D-MOCNs) showing high adaptability to surface step edges and structural defects is revealed by scanning tunneling microscopy. Rod-like 4,4'-di-(1,4-buta-1,3-diynyl)-benzoic acid (BDBA) iron atoms assemble into 2D-MOCNs on Au(111) Ag(100) surfaces. Independent from the chosen substrate its symmetry MOCN grows continuously over multiple terraces through mutual in-phase structure adaptation network domains at as well terraces. MOCNs mainly ascribed degree conformational flexibility butadiynyl functionality ligand. Despite their flexibility, exhibit considerable robustness against annealing temperatures. findings show that mesoscale self-assembled functional architectures with a error tolerance can be realized metal networks.
