Structural change accompanying electrochemical oxidation of [(η5-C5Me5)2Fe2S4] to [(η5-C5Me5)2Fe2S4](PF6)2
Abstract
Electrochemical oxidation of [(η5-C5Me5)2Fe2S4] in MeCN containing NH4PF6 affords [(η5-C5Me5)2Fe2S4](PF6)2 in which a bidentate µ-S2 ligand in the parent complex is converted to a doubly bidentate µ-S2 ligand; the structure of the resulting Fe2S4 core can be described as a distorted octahedron, as shown by an X-ray crystal structure determination.
