2,9-Dimethyl-6H,13H-5:12,7:14-dimethanodibenzo[d,i][1,3,6,8]tetraazecine

Abstract

In the title structure, C18H20N4, the aromatic rings are almost orthogonal [81.6 (2)°]. The molecule has symmetry 2 since it is situated on a crystallographic twofold axis. There are only weak intermolecular interactions present in the structure, notably C—H...π-electron ring interactions. The 1H and 13C NMR spectra are in accordance with the X-ray structure analysis.
