Abstract
Two binuclear bis(tricarbonyliron) title complexes with N2Fe2 tetrahedral cores, 1 and 2, respectively, which show different molecular folding resulting from the appearance (in 1), and absence (in 2) of the NN σ‐bond, were compared in terms of mass spectral fragmentation routes. A multipath fragmentation noted for the molecule 1 revealing internal stress contrasts with the single‐route fragmentation of 2. The fragmentation paths resulting from the admixtures were defined and analyzed from the fragment ion B/E and parent ion B2/E linked scan spectra. Copyright © 2002 John Wiley & Sons, Ltd.
