Field desorption mass spectrometry of a series of various metal carbonyl 1,4-diazabutadiene compounds

Abstract

It is shown that field desorption mass spectrometry is a useful method of characterizing the thermally labile and involatile organometallic complexes mentioned in the title. In most cases only molecular ions are generated, but in some cases also (M@?CO)}+{}.{ fragment ions are observed.
