摘要：

The structure of the dication of tetramethoxythianthrene (1) can be described as two nine-membered cyanine units coupled by C-C single bonds. This shows that the tendency for a cyanine-like structure perturbation is very great, since 1(2)+ still contains two electrons too many for real cyanine subsystems and could alternatively have exhibited aromatic character as heteroanthracene.
