2,3-Bis(phenoxymethyl)buta-1,3-diene

Abstract

The mol­ecule of the title compound, C18H18O2, a symmetrically phenol-substituted divinyl analog, exhibits crystallographically imposed C 2 symmetry. The phenolic and divinyl planar groups inter­sect each other orthogonally, with a dihedral angle of 82.7 (1)°. The structure is stabilized by a short intra­molecular C—H⋯O contact. The mol­ecules are held together by C—H⋯π inter­actions, forming a sheet structure parallel to the (201) plane.
