Abstract

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) Å and is an archetypical example of a dative S^IV ← N bonding modality.
