A novel 2D coordination bimetallic framework composed of Cu and Zn is obtained at a Au(111) surface by the supramolecular assembly of Cu and zinc‐5,10,15,20‐tetra(4‐pyridyl)porphyrin molecules (see figure). Suppressing Cu concentration at high temperature transforms the 2D bimetallic frameworks into 2D homo‐metallic hydrogen‐bond arrays. Enriching the Cu concentration can reverse the structural transformation.
