The crystalline form of 4-methoxy-6-(1′,2′-dihydrostyryl)-5,6-dihydro-α-pyrone is assigned to space group P21/cC2h5 having parameters a = 10.921, b = 7.605, c = 17.014 Å and β = 119°30′. The crystal structure was found by phase assignment with the symbolic-addition procedure. The resulting E map showed the whole molecule. The refinement by the block-diagonal-matrix least squares led to a R value of 0.09 using 2352 reflections. A short discussion of the structure is given.
