Crystal structure of 1-methoxypyrene

Abstract

The title compound, C17H12O, crystallized with three independent molecules (A, B and C) in the asymmetric unit. In the crystal, the three independent molecules are linked by π–π interactions [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 interactions generating a laminar arrangement parallel to (010). The methoxymethyl group in molecule A is disordered over two sets of sites, with an occupancy ratio of 0.56 (9):0.44 (9).
