Molecular structure of bis(trifluoromethyl)hydroxylamine : an electron diffraction study

Abstract

The molecular structure of bis(trifluoromethyl)hydroxylamine, (CF₃)₂NOH, has been determined in the vapour phase by the sector microphotometer electron diffraction method. Principal structural parameters with estimated standard deviations in parentheses are: r(N–O) 1·40(3), r(C–N) 1·435(fixed), and r(C–F) 1·322(2)Å; F–C–F 109·8(0·4), C–N–C 120·6(1·3), C–N–O 111·3°(0·8°). The longer N–O bond and smaller sum of angles at nitrogen than in (CF₃)₂NO result in rather similar F⋯O distances in the two molecules.
