Données cristallographiques de la dihydro-10,11 (quinuclidinyl 3)-5-5H-dibenzo[b, f]azépine (quinupramine)

In iminodibenzyl, C₁₄H₁₃N, when a quinuclidinyl radical, –C₇H₁₂N, takes the place of the amino hydrogen atom the space group is unchanged. Crystals of C₂₁H₂₄N₂ are monoclinic, P2₁/c, with lattice constants a = 12.97 (2), b = 15.79 (2) and c = 7.99 (1) Å, β = 91.5 (1)°; Z = 4, D_x = 1.23 Mg m⁻³. X-ray powder diffraction data are reported.
