Encapsulated SA structures also appear in larger clusters, first observed in the (SA) 14 (AM) 14 and (SA) 15 (DMA) 15 systems. This suggests that SA has a lower propensity for encapsulation in clusters compared to amininium or ammonium ions. Notably, as the cluster size increases, encapsulation eventually becomes more prevalent. However, it is important to note that an encapsulated structure is not always the most stable configuration.
