N2 - The synthesis of pyrrolidinium pentaborate(1-) and four substituted pyrrolidinium pentaborate(1-) salts from B(OH)3 in aqueous solution are reported. Characterization (Infrared, nuclear magnetic resonance, and single-crystal X-ray power diffraction) of [(2-HOCH2CH2)C4H7NH2] [B5O6(OH)4]0.3H2O is described in detail. The cation is the largest of the five pyrrolidinium cations studied. A consequence of this is that its solid-state structure has anion–anion interactions (αααγ), which are different from the other four (αααβ) structures. There are also stabilizing cation–anion H-bond interactions.
