Fig. 4. The local differential charge density plots and corresponding 2D data display plots for the 2nd case. (a) G–Sc, (b) G–Ni, (c) G–Co, (d) GY–Ti and (e) GY–Cu. The bottom row represents the bond lengths between carbon atoms and metal atoms. The saturation levels are from −0.01 to 0.01 e Å−3. The yellow (red)/blue colours mark an increase/decrease of the charge density, respectively.
