Abstract
Ionisation energies have been determined for N3P3FnX6−n where n = 2, 3 and 4 and X = Br, Cl or NMe2, using an electron impact ion source and the semi-logarithmic plot method. Results are compared with values for N3P3X6 where X = Br, Cl, F or NMe2. The substitution of dimethylamino groups for fluorines in N3P3F6 causes a marked decrease in ionisation energy. A similar though less pronounced decrease occurs on substitution of fluorine by bromine or chlorine. The appearance energies were determined for several fragment ions.
