Homogeneous iron complexes for the conversion of dinitrogen into
... The binding of dinitrogen to a metal centre is believed to be crucial for the functionalisation of dinitrogen as it weakens the strong NRN bond. The interaction between a metal centre and dinitrogen involves both s and p components as shown in Fig. 2. The dinitrogen is able to bind as a Lewis base a ...
