Structures and Properties of Dinitrosyl Iron and Cobalt Complexes Ligated by Bis(3,5-diisopropyl-1-pyrazolyl)methane
Two dinitrosyl iron and cobalt complexes [Fe(NO)<sub>2</sub>(L1”)](BF<sub>4</sub>) and [Co(NO)<sub>2</sub>(L1”)](BF<sub>4</sub>) are synthesized and characterized, supported by a less hindered bidentate nitrogen ligand bis(3,5-diiso...

| description | Two dinitrosyl iron and cobalt complexes [Fe(NO)<sub>2</sub>(L1”)](BF<sub>4</sub>) and [Co(NO)<sub>2</sub>(L1”)](BF<sub>4</sub>) are synthesized and characterized, supported by a less hindered bidentate nitrogen ligand bis(3,5-diisopropyl-1-pyrazolyl)methane (denoted as L1”), are surprisingly stable under argon atmosphere. X-ray structural analysis shows a distorted tetrahedral geometry. Spectroscopic and structural parameters of the dinitrosyl iron and cobalt complexes are consistent with the previous reported {Fe(NO)<sub>2</sub>}<sup>9</sup> and {Co(NO)<sub>2</sub>}<sup>10</sup>. Two N−O and M−N(O) stretching frequencies and their magnetic properties are also consistent with the above electronic structural assignments. We explored the dioxygen reactivities of the obtained dinitrosyl complexes. Moreover, the related [FeCl<sub>2</sub>(L1”)], [Co(NO<sub>3</sub>)<sub>2</sub>(L1”)], and [Co(NO<sub>2</sub>)<sub>2</sub>(L1”)] complexes are also characterized in detail. |
