Reaction of a functional biferrous heme/nonheme model complex at low temperature leads
to the formation of a distal nonheme nitrosyl followed by a trans heme nonheme bis-nitrosyl
intermediate. The EPR and Raman data on this intermediate indicate that the two nitrosyl
centers are close. This complex gives off N2O and provides support for the trans mechanism
proposed for NOR enzymes.
