The double cages oxide C~1~2~0O was investigated by INDO series methods, the results suggested that: the formation of C~1~2~0O reduced the angle constraint at the three-membered ring of epoxide in C~6~0O and the furane ring connected the two C~6~0 cages together. The direct connection of the two C~6~0 cages rendered the two cages interact weakly to each other, however, the two cages still behaved with certain independence to each other. C~1~2~0O could discompose to new compounds. the electronic spectra of C~1~2~0O were analogous to those of parent C~6~0.
