More interestingly, the Laplacian values in all systems were investigated (refer to Figure ). Notably, the values obtained for all the systems analysed were found to be lower compared to those corresponding to the ionic complexes. The general results from these analyses are in perfect agreement with the findings obtained from both previously studied models, guanidinium-based and ammonium-based. They demonstrate an intermediate behaviour between HB-assisted ion-pair and longer-range ion-pair interactions, underscoring the consistency and validity of the conclusions drawn from this analysis.
