The  anion is less nucleophilic and basic (and therefore more weakly coordinating) than nitrates, halides or even triflates. Thus, when using salts of , one can usually assume that the cation is the reactive agent and this tetrahedral anion is inert.
Due to its lower nucleophilic and basic properties, the anion tends to be a weaker ligand compared to nitrates, halides, or triflates. In the context of using salts of this anion, it is generally safe to assume that the cation plays a more significant role in chemical reactions, while the tetrahedral anion remains relatively unreactive.
