## Abstract The molecular structure of the vinylogous 4__H__βpyrone 2,6βdimethylβ4β(2βoxopropylidene)β4__H__βpyran (**1**) was determined by Xβray diffraction. The molecule is practically planar and has the __sβcis__ conformation. The experimental dipole moment (3.71 D) of **1** agrees with the CND
