Abstract
In quinuclidine-trifluoroborane a crystallographic mirror plane bisect s the staggered quinuclidine and boron trifluoride groups. The B-N dis tance [1.601 (7) angstrom] is identical to that in pyridine-trifluorob orane [1.602 (4) angstrom; Topel, Hensen & Bats (1984). Acta Cryst. C4 0, 828-8301 despite the markedly lower basicity of the aromatic amine [pK(a) 5.25 (H2O, 298 K) versus 10.95 for quinuclidine].
