%X Two dinitrosyl iron and cobalt complexes [Fe(NO)2(L1¡±)](BF4) and [Co(NO)2(L1¡±)](BF4) 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)2}9 and {Co(NO)2}10. Two N¨CO and M¨CN(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 [FeCl2(L1¡±)], [Co(NO3)2(L1¡±)], and [Co(NO2)2(L1¡±)] complexes are also characterized in detail.
