title: 14-(2,3-Dichloro-phen-yl)-9,10-dimethyl-benzimidazo[1,2-a]benzo[f][1,8]naphthyridine-6-carbonitrile.
abstract: In the title compound, C(27)H(16)Cl(2)N(4), the benzimidazo[1,2-a]benzo[f][1,8]naphthyridine system is nearly planar (r.m.s. deviation for all non-H atoms = 0.033 Å). The dichloro-phenyl substituent is rotated by -67.5 (2)° from this plane. In the crystal structure, mol-ecules form stacks along the crystallographic (100) direction due to π-π stacking inter-actions with a centroid-centroid distance of 3.4283 (9) Å.
