1,3-Bis(propan-2-yl)naphthalene

In the title compound, C(16)H(20), one of the isopropyl groups shows almost equal displacements [1.252 (1) and −1.270 (1) Å] of its methyl-C atoms from the mean plane of the naphthalene ring system, while the other shows asymmetric displacements [1.586 (2) and −0.315 (1) Å]. In the crystal, the mol­ecules are linked into sheets lying in the ab plane by three C—H⋯π contacts, two involving donors belonging to the isopropyl groups and the third a donor atom from the naphthalene ring system. The different orientations of the isopropyl groups might be attributed to the fact that the C—H⋯π inter­action involving one of them is enhanced by the C—H⋯π inter­action involving the aromatic ring.
