Hirshfeld surfaces of phenylacetate (top), benzylammonium (middle) and water (bottom) molecules in 2 mapped with dnorm. Red spots indicate contact areas shorter than the van der Waals separation. Contacts can be attributed to the following intermolecular interactions: O3—H32⋯O2 (A/A′), O3—H31⋯O2 (B/B′), N—H12⋯O1 (C/C′), N—H11⋯O1 (D/D′), N—H13⋯O3 (E/E′), C9—H9B⋯O3 (F/F′), C15—H15⋯O2 (G/G′), C5—H5⋯C1 (H/H′) and C9—H9A⋯C4 (I/I′). The map ranges from −0.6666 to 1.2024 a.u. for phenylacetate, −0.6268 to 1.1600 a.u. for benzylammonium and −0.6680 to 1.0780 a.u. for water.
