In the title compound, C16H20, one of the isopropyl groups shows almost equal displacements [1.252 (1) and -1.270 (1) angstrom] 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) angstrom]. In the crystal, the molecules are linked into sheets lying in the ab plane by three C-H center dot center dot center dot pi 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 center dot center dot center dot pi interaction involving one of them is enhanced by the C-H center dot center dot center dot pi interaction involving the aromatic ring.
