Synthesis of cis ‐ and trans ‐[Fe(CN) 2 (CN t Bu) 4 ] in a One‐Pot Procedure from Fe 2 (CO) 9 and tert. Butylisocyanide The reaction of Fe 2 (CO) 9 with tert. butyl isocyanide in the presence of 10 bar of carbon monoxide leads to the formation of the mononuclear trigonal bipyramidal compound [Fe(CO) 3 (CN t Bu) 2 ] with two axially coordinated isocyanide ligands. If the same reaction is carried out without additional carbon monoxide being present in the solution, a 1:1 mixture of the isomeric octahedral complexes cis ‐ and trans ‐[Fe(CN) 2 (CN t Bu) 4 ] is produced via a complex redox reaction involving the reductive cleavage of isocyanide ligands. The molecular structures of the product compounds is going to be discusssed. The crystal structures of cis ‐ and trans ‐[Fe(CN) 2 (CN t Bu) 4 ] are mainly determined by the ability of the cyano ligands to act as hydrogen bond acceptor sites.
