complexes, crystalline bis(morpholinedithiocarbamato-S,S')mercury(II) with the pseudo-1D-polymeric structure, is preparatively synthesized. The structure is characterized by 13С and 15N MAS NMR spectroscopy and X-ray diffraction analysis (CIF file CCDC no. 1821609). Pairs of symmetric secondary Hg⋅⋅⋅S bonds (3.400 Å) combine mononuclear [HgS2CN(CH2)4O}2] molecules, including planar polygons [HgS4], into
摘要制备了具有代表性的1D-聚合物结构的双(吗啉代二硫代氨基甲酸酯-S,S ')汞(II)晶体,它是二硫代氨基甲酸汞(II)络合物的新代表。该结构的特征在于13 C和15 N MAS NMR光谱学和X射线衍射分析(CIF文件CCDC号1821609)。成对的对称Hg⋅⋅⋅S双键(3.400Å)结合了单核[Hg S 2 CN(CH 2)4 O} 2)分子,包括平面多边形[HgS 4],变成线性的假聚合物链。对热行为的研究表明,通过热重分析法检测到的两阶段质量损失是由于配合物的热破坏以及HgS的形成及其随后的升华。
