Abstract
The valence isoelectronic imido analogue H 2 S(N t Bu) 4 ( 1 ) of sulfuric acid H 2 SO 4 was synthesized, isolated and characterized by NMR spectroscopy and high-resolution X-ray charge density analysis. The latter reveals strongly polarized S δ+ -N δ- bonds with virtually no double bond character. The easy-to-polarize S-N bonds are an advantageous and versatile feature of sulfur nitrogen ligands to adapt to different electron requirements of various metal cations.
