2,3-Bis[(2-methylphenoxy)methyl]buta-1,3-diene

Abstract

The mol­ecule of the title compound, C20H22O2, a symmetrically 2-methyl­phenol-substituted divinyl analog, exhibits crystallographically imposed C 2 symmetry. The mol­ecular structure is essentially planar. The structure is stabilized by a short inter­molecular C—H⋯O contact. Cooperative C—H⋯π inter­actions generate an infinite one-dimensional chain of mol­ecules along the a axis.
