How to design a fast two-electron transfer: structural rearrangement in the second electron transfer provides stabilization

Abstract

The X-ray crystal structure of [(FeC5Me5)2(µ2,η10-biphenyl)]+PF6–,(1)+, shows a 37-electron configuration indicating that the two-electron transfer (1)2+(36e)→(1)+(37e)→(1)(36e) proceeds with structural reorganization and stabilization in the second electron transfer.
