C24H24N2, M(r) = 340.5, tetragonal, I4(1), a = 11.872 (2), c = 13.746 (3) Å, V = 1937.5 (5) Å3, Z = 4, D(x) = 1.17 g cm-3, Mo K-alpha, lambda = 0.71069 Å, mu = 0.63 cm-1, F(000) = 728, room temperature, R = 0.043 for 736 reflections with I > 3-sigma-(I). The dihedral angle between the planes of the naphthylic rings is 71.2(1)-degrees. The N atoms in the dimethylamino groups are almost sp2 hybridized
