The EI mass spectra of seven 1,1′‐(3‐oxa‐pentamethylene)‐dicyclopentadienyl lanthanide and yttrium chlorides ( 1–7 ), and eleven dicyclopentadienyl lanthanide and yttrium chlorides ( 8–18 ) were investigated. Fragmentation patterns of these complexes were studied by using metastable ion measurements. The EI spectra of complexes 1–7 exhibited strong molecular ion peaks, the fragmentation of molecular ions were more complicated. The EI mass spectra of complexes 8–18 supported the dimeric structure under gaseous state. In the spectra of dimers (C 5 H 5 ) 3 LN + observed were resulted from the skeletal rearrangement involving the migration of cyclopentadienyl moiety.
