Abstract

Monocrystals of the trans and cis isomers of 3-cyano-4-[2-(4-methoxyphenyl)vinyl]-6,6-dimethyl-5,6-dihydro-2H-pyran have been obtained and an X-ray  structural analysis of them has been carried out. Both compounds have a molecular structure corresponding to symmetry group C1. The heterocyclic ring is in a distorted envelope conformation. The crystals of the trans isomer are rhombic and have a
fir-tree type of packing. The crystal packing of the cis isomer is formed by pairs of molecules, each of which consists of only one enantiomer.
