Abstract
Abstract The valence isoelectronic imido analog H 2 S(NtBu) 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, which enables them to adapt to different electron requirements of various metal cations.
