Crystal structure of 3-[4-(1-methyl-eth-yl)phen-yl]-1-(naphthalen-2-yl)prop-2-en-1-one.

The title compound, C22H20O, was synthesized by reacting 4-iso-propyl-benzaldehyde with 2-acetonaphtone by aldolic condensation under Claisen-Schmidt conditions. The mol-ecule consists of a naphthalene group and a benzene ring with a pendant isopropyl moiety, both rings bound by a propenone linker. The naphthalene ring system is almost planar [maximum deviation from the least-squares plane = 0.
