Abstract New phosphines1–3 have been synthetized by reaction of pyrazolate anion with tris(pentafluorophenyl)phosphine and characterized by1H,31P, and19F NMR studies.19F NMR spectral data contribute to the evidence for apara-substitution of tetrafluorophenyl rings. The crystal structure of tris(4-pyrazol-1-yl-2,3,5,6-tetrafluorophenyl)phosphine 1 has been determined, proving that the assignment based on spectroscopic data was correct: C27H9F12N6P,M r = 676.37, monoclinic, space group P2l/c,a=10.754(2) å,b=10.316(2) å,c = 23.598(5) å,Β=95.36(3)
