It crystallized in orthorhombic space group Pcab, with cell parameters: a = 10.579 (3), b = 18.514(7) , c = 23.93(1) ?, V = 4686.22(3) ?3, Z = 8, Dc = 1.223g/cm3, F(000) = 1840, μ = 0.68mm-1. The structure was solved by direct methods and refined by full-matrix least-squares method, and final R = 0.057, Rw = 0.060 for 2282 observed reflections with I ≥3.00σ(I). The molecular backbone is aza-bicycle [3,2,1]octane containing a chair-like six-membered aza-cycle conformation.展开更多
