Sulfur tetrafluoride and triethylamine react at low temperatures to form a 1 : 1 adduct. The unambiguous characterization of the SF4 N(C2H5)3, which is only stable at low temperature, proves the Lewis acid property of SF4 towards organic Lewis bases. The S–N bond has a length of 2.384(2) A ̊ and is an archetypical example of a dative SIV ’N bonding modality
