crystal data
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, Dx = 1.23 Mg m−3. X-ray powder diffraction data are reported.
