2,9-Dimethyl-6H,13H-5:12,7:14-dimethano-dibenzo[d,i][1,3,6,8]tetraazecine
Abstract:
In the title structure, C(18)H(20)N(4), the aromatic rings are almost orthogonal [81.6 (2)°]. The mol-ecule has symmetry 2 since it is situated on a crystallographic twofold axis. There are only weak inter-molecular inter-actions present in the structure, notably C-H⋯π-electron ring inter-actions. The (1)H and (13)C NMR spectra are in accordance with the X-ray structure analysis.
