The dinitrosyliron complex [Fe4(μ3-S)2(μ2-NO)2(NO)6]2− containing bridging nitroxyls: 15N (NO) NMR analysis of the bridging and terminal NO-coordinate ligands†
Abstract
The fluxional terminal and semibridging NO-coordinate ligands of DNIC [Fe4(μ3-S)2(μ2-NO)2(NO)6]2−, a precursor of Roussin's black salt (RBS), are characterized by IR ν(NO), 15N (NO) NMR and single-crystal X-ray diffraction.
