Abstract: In the asymmetric unit of the title compound, C₁₉H₁₆O₂, there are two symmetry-independent molecules (A and B) that differ in the conformation of the ester ethoxy group. In the crystal, the molecules form inversion dimers via pairs of C-HO interactions. Within the dimers, the anthracenyl units have interplanar distances of 0.528 (2) and 0.479 (2) Å for dimers of molecules A and B, respectively. Another short C-HO contact between symmetry-independent dimers links them into columns parallel to [10-1]. These columns are arranged into (111) layers and there are [pi] - [pi] stacking interactions [centroid-centroid distances = 3.6446 (15) and 3.6531 (15) Å] between the anthracenyl units from the neighbouring columns. In addition, there are C-H [pi] interactions between the anthracenyl unit of dimers A and dimers B within the same column.
