Im. Atkinson et al., NEW MACROCYCLIC LIGANDS .5. SYNTHETIC, CRYSTALLOGRAPHIC AND COMPUTATIONAL STUDIES OF A NEW N2O6-HETEROATOM CAGE, Australian Journal of Chemistry, 47(6), 1994, pp. 1155-1162
The synthesis, characterization and X-ray structure of a new cage mole
cule containing six phenoxy and two nitrogen heteroatoms is reported.
Semiempirical MO calculations have been used to probe the topological
rigidity of the cage relative to related aliphatic systems.
