Mutual influence between anion-π and pnicogen bond interactions: The enhancement of P⋯N and P⋯O interactions by an anion-π bond

- The interplay between anion-π and pnicogen bond interactions is studied.
- The cooperative energy ranges from −1.8 to −4.1 kcal mol−1.
- The complexes in which weaker Pn-bond is present exhibit strong cooperativity.
- When the anion is F−, shortening of P⋯N/O appears more pronounced.
