Description |
797-798
The electron impact mass spectrum of Mo<sub>2</sub>(S<sub>2</sub>PF<sub>2</sub>)<sub>4</sub> shows the molecular ion which releases a PF<sub>2</sub> group to produce the most abundant ion, Mo<sub>2</sub>S<sub>8</sub>P<sub>3</sub>F. This ion fragments by releasing a series of groups such as PF<sub>2</sub>, PFS and PF<sub>2</sub>S, For Mo<sub>2</sub>(S<sub>2</sub>PMe<sub>2</sub>)<sub>4 </sub> Desorption Chemical Ionization (DCI) technique is required to see the molecular ion. The parent ion fragments by the loss of Me<sub>2</sub>S, PMe<sub>2</sub>S and PMe<sub>3</sub> groups. Loss of PMe<sub>3</sub> from molecular ion suggests rearrangement before fragmentation-a process not observed for Mo<sub>2</sub>(S<sub>2</sub>PF<sub>2</sub>)<sub>4</sub>. The difference in mass spectral fragmentation patterns is in agreement with the different structures of the two compounds. |
