(a,b) Geometric structures of pyridazine binding to Ge dimer atoms through double N–Ge bonds (a) or a single N–Ge bond (b). (c) Simulated STM images of a at a bias of −2.0 V. (d) STM image of the lucky-clover feature adapted from Fig. 1d. (e) Simulated STM images of b at biases of −2.0 V and (g) −0.5 V. (f) STM image of the clover feature adapted from Fig. 1b at biases of −2.0 V and (h) −0.5 V (from Fig. 1c). All scale bar, 0.8 nm. The colour bar legends are in the unit of e Å−3.
