Inhaltszusammenfassung
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)((CNBu)-Bu-t)(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)((CNBu)-Bu-t)(4)] is produced via a complex redox reaction involving ...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)((CNBu)-Bu-t)(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)((CNBu)-Bu-t)(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)((CNBu)-Bu-t)(4)] are mainly determined by the ability of the cyano ligands to act as hydrogen bond acceptor sites. » weiterlesen» einklappen
