1-Methoxy-11H-benzo[b]fluoren-11-one

Abstract

In the title compound, C18H12O2, the non-H atoms are nearly coplanar, the maximum atomic deviation being 0.113 (2) Å. π–π stacking is observed in the crystal structure, the shortest centroid–centroid distance being 3.5983 (19) Å. The molecular packing is further stabilized by weak C—H...O hydrogen bonds, forming an infinite chain along [100] and generating a C(6) motif.
