one‐electron oxidation of Fe‐redox centre. As an example, the chirality of 3c was investigated by 31P NMR spectroscopy on the addition of (R)‐(+)‐2,2,2‐trifluoro‐1‐(9′‐anthryl)‐ethanol, chiral solvating agent (CSA). The circular dichroism (CD) (for 3d and 3e), HPLC (for 3d, 3e and 3f) and X‐ray (for 3f) display that these compounds have chirality (RS′ or SR′) in the solution and solid state. This paper
