{"doi":"10.1002/ange.202109062","title":"A Nonheme Mononuclear {FeNO}<sup>7</sup> Complex that Produces N<sub>2</sub>O in the Absence of an Exogenous Reductant","abstract":"Abstract A new nonheme iron(II) complex, Fe II (Me 3 TACN)((OSi Ph2 ) 2 O) ( 1 ), is reported. Reaction of 1 with NO (g) gives a stable mononitrosyl complex Fe(NO)(Me 3 TACN)((OSi Ph2 ) 2 O) ( 2 ), which was characterized by Mössbauer ( δ =0.52 mm s −1 , |Δ E Q |=0.80 mm s −1 ), EPR ( S =3/2), resonance Raman (RR) and Fe K‐edge X‐ray absorption spectroscopies. The data show that 2 is an {FeNO} 7 complex with an S =3/2 spin ground state. The RR spectrum ( λ exc =458 nm) of 2 combined with isotopic labeling ( 15 N, 18 O) reveals ν(N‐O)=1680 cm −1 , which is highly activated, and is a nearly identical match to that seen for the reactive mononitrosyl intermediate in the nonheme iron enzyme FDPnor (ν(NO)=1681 cm −1 ). Complex 2 reacts rapidly with H 2 O in THF to produce the N‐N coupled product N 2 O, providing the first example of a mononuclear nonheme iron complex that is capable of converting NO to N 2 O in the absence of an exogenous reductant.","journal":"Angewandte Chemie","year":2021,"id":228931,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9329,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":719338,"name":"Jesse B.
