title: N-(4,5-Diaza-9H-fluoren-9-yl-idene)-4-meth-oxy-aniline.
abstract: In the title compound, C(18)H(13)N(3)O, the diaza-fluorene ring system is almost coplanar (r.m.s. deviation = 0.0640 Å) and subtends an angle of 61.5 (4)° with the plane of the meth-oxy-substituted benzene ring. In the crystal structure, pairs of C-H⋯O hydrogen bonds link mol-ecules into centrosymmetric dimers parallel to the ab plane. Mol-ecules are also stacked in an obverse fashion along the c axis by a variety of π-π inter-actions with centroid-centroid distances in the range 3.557 (2)-3.921 (2) Å.
