We report proton transfer in the complex H3N···HCl to form the
ion pair NH4
+Cl, which is favored inside the C60 cage according
to quantum chemical calculations. The results show that
the NH4
+Cl@C60 is stable with an interaction energy of
2.78 kcalmol1. Compared with the complex H3N···HCl without
proton transfer, it is found that the C60 cage plays the role
of a catalyst for proton transfer. In NH4
+Cl@C60 a negative
charge area in the C60 cage is near the cation NH4
+ whereas a
positive charge area is near the anion Cl.
