Crystal structure of 8-hex-yloxy-2-[(Z)-2-(naph-thal-en-2-yl)ethen-yl]quinoline

Abstract

In the title mol-ecule, C₂₇H₂₇NO, the naphthalene and quinoline groups are both planar and subtend a dihedral angle of 15.47 (7)°. They are nearly coplanar with the cis-vinyl bridge and the hex-yloxy chain, which adopts an all-trans conformation, resulting in transannular bifurcated intra-molecular C-H⋯N,O contact. The crystal structure features γ-packing of the aromatic moieties, while the parallel packing of alkyl chains resembles that of alkanes.

Keywords: crystal structure; intra-mol­ecular hydrogen bond; naphthalene derivative; quinoline derivative; γ-packing; π-conjugated; π–π inter­actions.
