The title compound, C17H12O, crystallized with three independent mol-ecules (A, B and C) in the asymmetric unit. In the crystal, the three independent mol-ecules are linked by π-π inter-actions [centroid-centroid distances = 3.551 (3)-3.977 (2) Å], which lead to the formation of trimers. Between the trimers there are a number of C-H⋯π inter-actions generating a laminar arrangement parallel to (010). The meth-oxy-methyl group in mol-ecule A is disordered over two sets of sites, with an occupancy ratio of 0.56 (9):0.44 (9).
