The D3h 3,5-dehydrophenyl cation (I), which may represent the structure of Cz3+ ions observed mass spectroscopically, illustrates double aromaticity: two different aromatic systems in orthogonal planes. Cyclic conjugated polyenes with 4n+2 electrons are aromatic. 1 A large number of such systems are
