Abstract
Abstract
The crystalline form of trans-δ-[p-methoxystyryl]-4-methoxy-α-pyron is assigned to space group P21/c–C
2h
5 having parameters a = 7.313, b = 7.480, c = 23.721 Å and β = 94°21′. The crystal structure was found from the Patterson diagramm using the special symmetry of the space group P21/c. The refinement by the block-diagonal-matrix least squares led to a R value of 0.07 using 2256 reflections. The molecules are approximately planar and are held together by van der Waals forces only.
