The electron ionisation mass spectrometric behaviour of a new series of hafnocene and zirconocene dialcoholates is discussed. Deprotonated moieties of borneol and fenchyl alcohol were used as σ‐ligands. These data are also compared to those of mass‐analysed ion kinetic energy spectroscopy of the molecular ions. Fragmentation patterns of the complexes in question give relevant information on their gas‐phase behaviour and also on the influence of the ligand structure on the decomposition pathways. The complexes in question appear to be promising metal‐organic chemical vapour decomposition precursors. Copyright © 1999 John Wiley & Sons, Ltd.
