A FRAGMENTATION STUDY OF SOME DIETHYLINDIUM CYCLIC IMIDES

The electron ionization mass spectrometric behaviour of a series of di ethylindium complexes with imino ligands derived from piperidine, pyrr olidine, azetidine, methylaziridine and dicyclopropylamine were invest igated. These data have been compared with those from mass-analysed io n kinetic energy spectrometry. Fragmentation patterns of the complexes in question give information relevant to their gas-phase behaviour as precursors for III-V semiconducting materials via metal-organic chemi cal vapour deposition. A comparison with analogous derivatives of dime thylindium is also discussed. (C) 1998 John Wiley & Sons, Ltd.
