striking. Although both compounds have a set of
four nitrogens held with their lone pairs directed out-
ward, 5 . + shows no more stability than an ordinary
tertiary amine cation, having completely irreversible cv
spectrum, an unusually positive EIl2value, and a first
ionization potential,5s20which is higher than that of ada-
matane itself.20 It is clear that the number of nitrogens
over which the positive charge can be spread is not as
important in observing the unique stability of 1.- and
2.+ as is the necessity for conjugating these nitrogens
with C-C single bonds in favorable geometry for n-ucc
interaction. Apparently the C-N bonds of 5, which are
in the best possible geometry for n-uCN interaction, sim-
ply are too low lying to interact effectively with the ni-
trogen lone pair electrons.2 ' 5
