Charge-transfer complex

A charge-transfer complex is a type of chemical structure formed when an electron is transferred from one molecule (the donor) to another (the acceptor), leading to the formation of a new, stabilized interaction between them. This process can result in the formation of a transient or more stable complex characterized by distinct electronic properties. Charge-transfer complexes are typically formed between a donor with a low ionization potential (which easily gives up electrons) and an acceptor with a high electron affinity (which easily accepts electrons).
