Conclusions

  1. 1.

    The thermal stability of binuclear o-metallic iron-carbonyl complexes of Schiff bases does not depend on the structure of the organic ligand. The trinuclear complex is somewhat more stable than the binuclear. Thermal decomposition of the complexes investigated occurs on heating in Ar in two stages, and in air in three. Fe2(o-C6H4CH2NCH2C6H5)·(CO)6 (I) and Fe2(o-C6H4CH2NC6H5)(CO)6 (III) complexes decompose with formation of volatile iron compounds.

  2. 2.

    The basic direction of the intial decay of binuclear complexes on heating and electron impact are elimination of the carbonyl ligands; for the trinuclear complex Fe3(o-C6H4CH2NC6H5)(CO)8 (V) along with elimination of the Fe(CO)2 fragment and the CO groups elimination of the organic ligand is also characteristic.
