Abstract

Two binuclear bis(tricarbonyliron) title complexes with N~2~Fe~2~ tetrahedral cores, 1 and 2, respectively, which show different molecular folding resulting from the appearance (in 1), and absence (in 2) of the NN 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 B^2^/E linked scan spectra. Copyright © 2002 John Wiley & Sons, Ltd.
