C-H center dot center dot center dot pi interactions in 9-(n-do-decylaminomethyl)anthracene

The title compound, C27H37N, which is intended to be included in the struct ure of a sulfonamide porphyrin for the preparation of Langmuir-Blodgett fil ms, consists of a dodecyl chain linked to an anthracene molecule through an aminomethyl group. The angle between the least-squares plane of the anthra cene and the dodecyl chain is 11.44 (8)degrees. The molecules are arranged in zigzag layers head-to-head, with the hydrocarbon chains side-by-side. Th e structure is stabilized by C-H...pi interactions, the strongest having an H...centroid distance of 2.63 Angstrom.
