The valence isoelectronic imido analog H S(NtBu) (1) of sulfuric acid H SO was synthesized, isolated, and characterized by NMR spectroscopy and high-resolution X-ray charge density analysis. The latter reveals strongly polarized S -N 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.
硫酸H₂SO₄的价电子等电子亚氨基类似物H S(NtBu)（1）已被合成、分离，并通过核磁共振光谱和高分辨率X射线电荷密度分析进行了表征。后者揭示了强烈极化的S -N键，几乎没有双键特征。易于极化的S-N键是硫氮配体的一个有利且通用的特性，这使它们能够适应各种金属阳离子不同的电子需求。
