摘要：

In quinuclidine-trifluoroborane a crystallographic mirror plane bisects the staggered quinuclidine and boron trifluoride groups. The B-N distance [1.601 (7) angstrom] is identical to that in pyridine-trifluoroborane [1.602 (4) angstrom; Topel, Hensen & Bats (1984). Acta Cryst. C40, 828-8301 despite the markedly lower basicity of the aromatic amine [pK(a) 5.25 (H2O, 298 K) versus 10.95 for quinuclidine].
