摘要：

With a 90-degrees twist between the two halves, dication 1(2+) is the first ethylene dication with the maximum distortion possible. The stabilization of the positive charge is achieved in the separate halves of the dication by delocalization over polymethine units. 1(2+). whose ClO4- salt melts at about 170-degrees-C with decomposition, is obtained from the electrochemical oxidation of 1. The structure of neutral 1 differs substantially from that of its dication.
