Nucleophilic Tendencies: The Mulliken analysis reveals (Table ) a consistent nucleophilic character for the platinum (Pt) atom under varying external pressures (0, 0.1333, 0.2667, and 0.4 Pa), with values of 0.176, 0.177, 0.176, and 0.176, respectively. These values indicate that Pt maintains its electron-donating ability across the pressure range, influencing the charge distribution around neighboring carbon atoms, specifically C2, C6, and C8. The induced charges for C2 are nearly invariant at 0.185, 0.184, 0.185, and 0.185; for C6, they are 0.231, 0.226, 0.231, and 0.231; and for C8, they remain steady at 0.185, 0.184, 0.185, and 0.185, respectively. These findings suggest that the nucleophilic influence of Pt promotes charge redistribution , which could enhance the interaction with electron-deficient species, a property essential for adsorption and catalytic reactions.
