Nickelocene adsorption on Cu(100) and on the tip apex. a STM image acquired with a metallic tip (5.6 × 5.6 nm2, −15 mV, 20 pA). b Counter image of the Cu atom obtained with a Nc-terminated tip (1.7 × 1.3 nm2, −15 mV, 20 pA). c Calculated relaxed configuration of a Nc molecule on top of a Cu adatom on Cu(100), together with the simulated STM image. Atom colors: Cu (yellow), C (gray), H (white) and Ni (green). d dI/dV spectra and their derivative acquired with a Cu-tip over a Nc molecule (solid blue line) and with a Nc-terminated tip over the Cu(100) surface (solid red line). Feedback loop opened at 100 pA and −15 mV
