The intermolecular N–N coupling of NO in a dinitrosyl iron complex (DNIC) induced by hydrogen bond donors in the secondary coordination sphere to form N2O is reported. A family of complexes containing pendant anilines in the secondary coordination sphere were synthesized and characterized. Reduction of the {Fe(NO)2}9 complex [Fe(PhNHPDI)(NO)2][BPh4] (3) to the {Fe(NO)2}10 Fe(PhNHPDI)(NO)2 (4) results in intermolecular N–N coupling to form N2O. Similar reactions of the control {Fe(NO)2}9 complex [Fe(PhNMePDI)(NO)2][BPh4] (7), which does not have H-bonding groups in the secondary coordination sphere, do not result in N2O formation. The hydrogen bonding capabilities of the complexes were explored spectroscopically and computationally.
