inner-sphere electron transfer

https://doi.org/10.1351/goldbook.I03052
Historically an electron transfer between two metal centres sharing a ligand or atom in their respective coordination shells. The definition has more recently been extended to any situation in which the interaction between the donor and acceptor centres in the transition state is significant (>20kJmol−1).
