摘要：
The molecular structures of the title compounds 3 and 5 were investigated by NMR and X-ray structural methods. The NMR results suggest two equivalent halves for both molecules. The X-ray study shows an approximate mirror plane for 3 and an approximate twofold axis for a significant portion of the macrocycle of 5.
