Figure 2
Contour map of the electron density ρ (brown contour lines) with the gradient vector field of ρ (green flux lines) in the vicinity of the P=O—Sn—Cl group. Bond and nuclear critical points are represented by blue and brown dots, respectively, while the purple bold lines are the bond paths (Bader, 2009) connecting nuclear critical points. The map was calculated and plotted using Multiwfn (Lu & Chen, 2012). |
