STM images of a the Kagome structure (in constant-height mode, V = 5 mV, I = 350 pA at the point marked by the cross, T = 77 K) and b the fishing-net structure (V = 100 mV, I = 20 pA, T = 77 K) formed by depositing 3 and Ce on Au(111), and c the chain-like structure (V = −1 mV, I = −50 pA, T = 4.3 K) formed by depositing 4 and Ce on Au(111). The unit cells of the Kagome and the fishing-net structures are highlighted by the white parallelograms in a and b. The 1D periodicity of the chain-like structure is marked by the white arrow in c. The structural motifs constructing the coordination structures are illustrated by the superimposed molecular models. Scale bars: a 2 nm, b 2 nm, and c 1 nm.
