## Abstract The molecular structures of the title compounds 3 and 5 were investigated by NMR and Xβray structural methods. The NMR results suggest two equivalent halves for both molecules. The Xβray study shows an approximate mirror plane for 3 and an approximate twofold axis for a significant port
