PhHgS(S)CNR2 [R = Me (6), Et (7)]. The compounds were investigated by multinuclear NMR spectroscopy (1H, 13C, 199Hg and 2D experiments) and mass spectrometry. The solid-state molecular structures of compounds 2–6 were established by single-crystal X-ray diffraction. In the compounds 2–5 the nitrogen atom of the pendant CH2NMe2 arm is strongly coordinated to the mercury atom. The (C,N)HgX core is non-planar
摘要[2-(Me2NCH2)C6H4] HgCl(1)与NH4Br和KI的反应分别得到类似的溴化物(2)和碘化物(3)。为了研究对悬挂臂氮原子的汞中心与潜在螯合阴离子配体的供体原子的竞争配位,二硫代氨基甲酸盐[2-(Me2NCH2)C6H4] HgS(S)CNR2 [R = Me(4),通过使1与Na [S 2 CNR 2]·nH 2 O(R = Me,n = 2; R = Et,n = 3)反应制备Et(5)。PhHgCl与相同的二硫代氨基甲酸钠之间的反应得到PhHgS(S)CNR2 [R = Me(6),Et(7)]。通过多核NMR光谱法(1H,13C,199Hg和2D实验)和质谱法研究了这些化合物。化合物2-6的固态分子结构是通过单晶X射线衍射建立的。在化合物2–5中,CH2NMe2侧链的氮原子与汞原子强烈配位。(C,N)HgX核在二硫代氨基甲酸酯4和5中是非平面的,因此汞原子成为立
