Abstract
Nitric oxide binds reversibly to the Fe(III) complex of a well-developed tetra-amido macrocyclic ligand. Reaction with NO results in formation of a species consistent with an S = 1 {Fe-NO}(6) ground state as characterized by UV-vis, IR, EPR, and Mössbauer spectroscopy. The resultant nitrosyl is labile and dissociates readily upon purging with N(2), thus providing a rare example of reversible NO binding to non-heme iron.
摘要
一氧化氮可与一种成熟的四氨大环配体的 Fe(III) 络合物可逆结合。与 NO 的反应生成了一种与 UV-vis、IR、EPR 和 Mössbauer 光谱一致的 S = 1 {Fe-NO}(6) 基态物种。所得的亚硝酰基不稳定，在用 N(2) 吹扫时容易解离，因此提供了非血红素铁可逆结合 NO 的罕见实例。
