The preparation and characterisation of some solid tetra-ethylammonium chlorofluorophosphates(V), (+)(-) (1<*>n<*>3), the anions of which were previously known only in mixed systems, are described for the first time.Their reactions with suitable metal pseudohalides (LiN3 or AgNCS) lead to substitution of the chlorine ligands only.In some instances ligand redistribution involving fluoride occurs.Some of the derivatives have also been prepared by ligand-exchange reactions between appropriate phosphate (V) anions.Several structural assignments have been made on the basis of the observed P-F splitting patterns and the pairwise additivity of 31P n.m.r. shifts, although fluxional behaviour was observed in some cases.All the pseudohalogeno-species are unstable, the thiocyanato-compounds isolated as solids decomposing readily at room temperature.
