Nitrosylation of the chelate-thiolate-containing dinitrosyliron complex (DNIC) (S(CH(2))(3)S)Fe(NO)(2) triggers nitric oxide (NO) activation to generate the homoleptic nitrosyl {Fe(NO)(2)}(9) DNIC Fe(NO)(4) (1) made up of two nitroxyls (or two NO anions) attached to a delocalized {Fe(NO)(2)}(9) motif. The significantly longer N3-O3/N4-O4 [1.380(12) and 1.280(12) Å] and Fe1-N3/Fe1-N4 [2.008(11) and 2.045(10) Ǻ] bond distances reflect that N3-O3 and N4-O4 of complex 1 may act as the nitroxyl-coordinated ligands. That is, the electronic structure of the DNIC 1 is best described as a {Fe(NO)(2)}(9) motif coordinated by two nitroxyl (NO(-)) ligands.
螯合硫醇基含二亚硝酰铁配合物（DNIC）(S(CH(2))(3)S)Fe(NO)(2)的亚硝酰化作用触发一氧化氮（NO）的激活，生成由两个连接在一个离域{Fe(NO)(2)}(9)基序上的硝酰基（或两个 NO 阴离子）组成的同核硝酰基{Fe(NO)(2)}(9)DNIC Fe(NO)(4)（1）。复合物 1 中较长的 N3-O3/N4-O4 [1.380(12) 和 1.280(12) Å]和 Fe1-N3/Fe1-N4 [2.008(11) 和 2.045(10) Ǻ]键距离反映出 N3-O3 和 N4-O4 可能作为硝酰基配位配体。也就是说，DNIC 1 的电子结构最好描述为由两个硝酰基（NO(-)）配体配位的{Fe(NO)(2)}(9)基序。
