资源简介：
Hydrotris(triazolyl)borate (Ttz) ligands form CuNOx (x = 2, 3) complexes for
structural
and functional models of copper nitrite reductase. These complexes
have distinct properties relative to complexes of hydrotris(pyrazolyl)borate
(Tp) and neutral tridentate N-donor ligands. The electron paramagnetic
resonance spectra of five-coordinate copper complexes show rare nitrogen
superhyperfine couplings with the Ttz ligand, indicating strong σ
donation. The copper(I) nitrite complex [PPN]+[(TtztBu,Me)CuINO2]− has
been synthesized and characterized and allows for the stoichiometric
reduction of NO2– to NO with H+ addition. Anionic Cu(I) nitrite complexes are unusual and are stabilized
here for the first time because Ttz is a good π acceptor.
