title: 12-(4-Meth-oxy-benzo-yl)-2-methyl-benzo[f]pyrido[1,2-a]indole-6,11-dione.
abstract: In the title compound, C(25)H(17)NO(4), the indolizine fused naphthaquinone unit is approximately planar [r.m.s deviation = 0.0678 Å] and makes a dihedral angle of 57.82 (5)° with the benzene ring of the meth-oxy-benzene group. The naphtho-quinone O atoms deviate, in the same sense, from the mean plane of the fused six-membered rings by 0.2001 (14) and 0.0516 (14) Å. In the crystal there is π-π stacking of inversion-related pairs of mol-ecules [inter-planar spacing = 3.514 (2) Å].
