Abstract
FOR most charge transfer complexes, the ground-state can be described chiefly by a non-bonding structure DA, as the contribution of the dative structure D+A− is rather small, where D is the electron donor and A is the electron acceptor. However, it has been shown1–3 for the complexes formed between aromatic diamines and substituted p- and o-benzoquinones that the dative or ionic state is the lowest one. These complexes may be regarded as salts, and can be prepared from salts, D+X− and M+A−, by a double decomposition reaction, where X− and M+ stand for inorganic ions.
