title: SF4·N(C2H5)3: the first conclusively characterized SF4 adduct with an organic base.
abstract: Sulfur tetrafluoride and triethylamine react at low temperatures to form a 1:1 adduct. The unambiguous characterization of the SF(4)·N(C(2)H(5))(3), which is only stable at low temperature, proves the Lewis acid property of SF(4) towards organic Lewis bases. The S-N bond has a length of 2.384(2) Å and is an archetypical example of a dative S(IV) ← N bonding modality.
