η-Cyclopentadienyl(nitrosyl)iron complexes containing group VA donors

Summary (-C₅H₅)Fe(NO)(CO)]₂ and (-C₅H₅)Fe(NO)(CO)I are formed when a slow stream of NO is passed through a benzene solution of (-C₅H₅)Fe(CO)₂]₂ and (-C₅H₅)Fe(CO)₂ I respectively. Similarly NO reacts with (-C₅H₅)Fe(CO)(Ph₃E)I and (-C₅H₅)Fe(CO)₂(Ph₃E)]I, where E = P, As and Sb, to give (-C₅H₅)Fe(NO)(Ph₃E)I and (-C₅H₅)Fe(NO)₂(Ph₃E)]I respectively. The complexes were characterized by elemental analyses and i.r. spectra.Reprints of this article are not available.
