Diaminodifluorophosphorane, PF2H(NH2)2, has been prepared by the reaction of chlorodifluorophosphine and ammonia, and has been characterised spectroscopically. Its vibrational spectra can be interpreted in terms of C2ν symmetry, with a trigonal-bipyramidal structure with axial fluorine atoms. N.m.r. spectra are consistent with this structure, and show that the amino-groups rotate rapidly at room temperature
