Abstract
It has been shown by X-ray structure analysis, 1 H NMR spectroscopy (including NOE) and PM3 calculations that symmetric isomers of the title compounds in the crystal and in solution have a Z , Z configuration stabilized by n N ,π interaction, but not the E,E configuration suggested earlier.Keywords
