N-(4,5-Diaza-9H-fluoren-9-ylidene)-4-methoxyaniline
Abstract
In the title compound, C18H13N3O, the diazafluorene 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 methoxy-substituted benzene ring. In the crystal structure, pairs of C—H...O hydrogen bonds link molecules into centrosymmetric dimers parallel to the ab plane. Molecules are also stacked in an obverse fashion along the c axis by a variety of π–π interactions with centroid–centroid distances in the range 3.557 (2)–3.921 (2) Å.
