Intermolecular N–NCoupling of a DinitrosylIron Complex Induced by Hydrogen Bond Donors in the Secondary CoordinationSphere
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 N<sub>2</sub>O is reported. A family of complexes containing pendant anilines in the secondary coordination sphere were synthesized and characterized. Reduction of the {Fe(NO)<sub>2</sub>}<sup>9</sup> complex [Fe(<sup>PhNH</sup>PDI)(NO)<sub>2</sub>][BPh<sub>4</sub>] (<b>3</b>) to the {Fe(NO)<sub>2</sub>}<sup>10</sup> Fe(<sup>PhNH</sup>PDI)(NO)<sub>2</sub> (<b>4</b>) results in intermolecular N–N coupling to form N<sub>2</sub>O. Similar reactions of the control {Fe(NO)<sub>2</sub>}<sup>9</sup> complex [Fe(<sup>PhNMe</sup>PDI)(NO)<sub>2</sub>][BPh<sub>4</sub>] (<b>7</b>), which does not have H-bonding groups in the secondary coordination sphere, do not result in N<sub>2</sub>O formation. The hydrogen bonding capabilities of the complexes were explored spectroscopically and computationally.
