Notes:
Mass spectra of complex compounds of niobium (V) and tantalum (V) of the type MCl2(OR)2L have been measured, where M = Nb and Ta; HL = 2,4-pentanedione, R = CH3, C2H5 and HL = Salicyladehyde, R = CH3. The fragmentation upon electron-impact depends on the nature of the ligands and to a minor extent on the central metal atom. A fragmentation scheme has been constructed on the basis of measurements of metastable transitions and accurate masses of important fragment ions. Rearrangement reactions involving hydrogen migration among ligands have been observed.
