• A series of monodiazadiene diolefin iron compounds, [Fe­(trop2dad)­(L)] (4; L = neutral ligand), has been prepared by one-electron oxidation of the FeI species [NaFe­(trop2dad)­(thf)3] (dad = diazadiene; trop = 5H-dibenzo­[a,d]­cyclohepten-5-yl). The electronic structures of compounds 4 were investigated by NMR and Mössbauer spectroscopy, single-crystal X-ray diffraction, solid- and liquid-phase magnetic susceptibility measurements, and DFT calculations. Compounds of type 4 with labile ligands L were found to be active (pre)­catalysts for the dehydrogenative coupling of (alkyl)­amine–boranes. Remarkably high activities were observed, especially for the homogeneous dehydrogenative polymerization of methylamine–borane.
