Figure 5
The electrostatic potential mapped onto the Hirshfeld surfaces within the isosurface value of −0.0416 to 0.0981 atomic units for (a) ⁴LH₂-I, (b) CBA-I, (c) ⁴LH₂-II and (d) CBA-II. The circles highlight the interactions between the electronegative sites of the amide and the chlorine atoms through the electropositive σ-hole region.
