The title salt, [(C2H5)(3)NH]+. C4H9F2NO5PS-, was the unexpected produ
ct in an attempted synthesis of [(CH3)(2)CHO]P-2(O)CF2SO2NH2 from [(CH
3)(2)CHO]P-2(O)CF2Br and hydroxylamine-O-sulfonic acid. Both the S and
P atoms are surrounded tetrahedrally, with the O-S-O and O-P-O bond a
ngles of 120.7(2) and 121.4(1)degrees, respectively, showing the great
est distortion from true tetrahedral geometry. The remaining bond dist
ances and angles have typical values, with the bond distances to C(1),
the fluorinated C atom, being slightly longer.
