Abstract
Twenty-seven difluorophosphates are successful ly prepared by the displacement reactions of anhydrous chlorides or arylcarboxylates with p u r i f i e d difluorophosphoric ac id . V ib ra t iona l spectra are obtained for these d i f l uo ro phosphates and assignments made. The effects of cation-anion in teract ions on the v i b r a t i o n a l frequencies of the PC^*^ 2 r o u P a r e a ^ s o examined. Mossbauer parameters for f ive d i a l k y l t i n bis-difluorophosphates are reported and compared with those of analogous f luorosulfa te de r iva t ives . E l e c t r i c a l conduct iv i ty , nuclear magnetic resonance and density studies of solut ions of some metal difluorophosphates i n difluorophosphoric acid are made i n an attempt to obtain a bet ter understanding of so lu t ion behaviour i n difluorophosphoric ac id .
