Isomerisation of [{Rh(µ-SR1)(η-C5H4R2)}2]:1H nuclear magnetic resonance and electrochemical studies and the X-ray crystal structure of [anti-{Rh(µ-SPh)(η-C5H5)}2]

Abstract
The isomerisation of [syn-{Rh(µ-SR1)(η-C5H4R2)}2] to the anti-isomer, the structure of which (R1= Ph, R2= H) has been elucidated by X-ray crystallography, involves opening of the Rh2S2 ring; insertion into the metal–metal bond to give [Rh2(µ-SR1)2(µ-X)(η-C5H4R2)2]+(X = SR1 or Cl) is initiated by one-electron oxidation.
