MnPc–NH3 on Pb(111). a Topography of a mixed island of MnPc–NH3 and MnPc molecules (setpoint: U = 50 mV, I = 100 pA; scale bar is 10 nm). The inset shows a zoom on seven MnPc–NH3 and two MnPc molecules (50 mV, 200 pA). b Characteristic dI/dV spectrum of an MnPc–NH3 (black) and on the bare Pb(111) (gray) acquired with a superconducting Pb tip (50 mV, 200 pA, U mod = 500 μVrms). c Zoom on the superconducting gap presenting a pair of YSR resonances (5 mV, 200 pA, 20 μVrms). The bound-state energy is indicated by ε and the tip gap by the gray area
