In 1887, more than a century after the synthesis of [Fe II (CN) 6 ] 4− , the complex [Fe II (CN) 5 (CO)] 3− , in which a CN − ligand is replaced by CO, was reported. It has taken an additional century for the synthesis of the complex in which a second CN − ligand is substituted by CO: trans ‐[Fe II (CN) 4 (CO) 2 ] 2− (structure shown). Remarkably, this anion is prepared by the simple reaction of FeCl 2 with NaCN and CO in water. [Fe(CN) x (CO) y ] complexes are of interest as models for the active site of hydrogenase enzymes.
