Figure 3
Contour map of the Laplacian of ρ in the vicinity of the P=O—Sn—Cl group. Solid red lines are isocontours with positive Laplacian (charge depletion regions) and dashed blue lines are isocontours with negative Laplacian (charge accumulation regions). Bond critical points and nuclear critical points are shown as blue and brown dots, respectively. The purple bold lines are the bond paths (Bader, 2009) connecting nuclear critical points in the map. The map was calculated and plotted using Multiwfn (Lu & Chen, 2012). |
