The N-B bond length is 1.4425 (15) A degrees, which is longer than a typical N-B bond because the nitrogen lone pair is not fully available to participate in the bond.eninfo:eu-repo/semantics/openAccessCrystal StructurePyrroloboraneN-B BondingPi DelocalizationArticle791505336628361WOS:0009101542000102-s2.0-85149363617N/A10.1107/S2056989022011768
