A series of stable paramagnetic organomercury compounds containing the 4,6-di-tert-butyl-N-(2,6-diisopropylphenyl)-o-iminobenzosemiquinone ligand (imSQ) with the general formula imSQHgR (R = Ph, Et, Prn, Bun, Pri, Hexc, CH2SiMe3, p-FPh, Fc, p-Me2NPh) were synthesized. The molecular and electronic structures of the synthesized compounds were investigated by EPR spectroscopy and X-ray diffraction. The
一系列稳定的顺磁性有机汞化合物,含有 4,6-二叔丁基-N-(2,6-二异丙基苯基)-o-亚氨基苯并半醌配体 (imSQ),通式为 imSQHgR (R = Ph, Et, Prn,合成了 Bun、Pri、Hexc、CH2SiMe3、p-FPh、Fc、p-Me2NPh)。通过EPR光谱和X射线衍射研究了合成化合物的分子和电子结构。邻亚氨基半醌配体显示出不寻常的酰氨基苯氧基型配位模式。在化合物 imSQHgR 的 EPR 谱中,磁性汞同位素 (199,201Hg) 的超精细耦合常数取决于取代基 R 的性质、温度和溶剂的性质。
