Comparison of cyanide and carbon monoxide as ligands in iron(II) porphyrinates

Angew Chem Int Ed Engl. 2009;48(27):5010-3. doi: 10.1002/anie.200901434.


Spot the difference: The five-coordinate iron(II) cyanoporphyrinates, which are spin-crossover compounds, can be used to synthesize previously unknown six-coordinate complexes. Bis(cyano) and (cyano)imidazole complexes are presented, and the five- and six-coordinate (cyano)iron(II) derivatives are compared with analogous CO complexes.
