Abstract
The title compound, C20H24B2F8N4, crystalises monoclinic (space group C2, Z = 4, a = 23.797(5) Angstrom, b = 8.330(2) Angstrom, c = 11.471(2 ) Angstrom, beta = 90.17(2)degrees. R = 0.084 for 1922 [1 greater than or equal to 2 sigma(I)]. The most notable features are the values of the C-C bond length [1.47(1) Angstrom], of the adjacent endocyclic N-C bond length [1.363(1) Angstrom] the torsion angle about the central C -C bond [83 degrees] and the nearly trigonal planar environment of the nitrogen atom.
