The title compound, C18H12N2O, comprises two aromatic fragments, viz., imidazo[2,1-a]isoquinoline and benzene, linked by oxygen and methylene bridges. Despite the absence of a common conjugative system within the molecule, it adopts an essentially planar conformation with an r.m.s. deviation of 0. 036 Å. In the crystal, due to this structure, molecules form stacks along the b axis by π...π stacking interactions, with shortest C...C distances in the range 3.340 (4)–3.510 (4) Å. The molecules are bound by intermolecular C—H...O interactions within the stacks and C—H...π interactions between the stacks.
