About: Mercury polycations

An Entity of Type: WikicatMercuryCompounds, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Mercury polycations are polyatomic cations that contain only mercury atoms. The best known example is the Hg2+2 ion, found in mercury(I) (mercurous) compounds. The existence of the metal–metal bond in Hg(I) compounds was established using X-ray studies in 1927 and Raman spectroscopy in 1934 making it one of the earliest, if not the first, metal–metal covalent bonds to be characterised. Other mercury polycations are the linear Hg2+3 and Hg2+4 ions, and the triangular Hg4+3 ion and a number of chain and layer polycations.

  • 多汞阳离子或多聚汞阳离子是仅含汞原子的原子团，最常见的多汞阳离子是Hg2+2，在亚汞化合物中存在。亚汞化合物中的Hg-Hg键通过1927年的X射线分析和1934年的拉曼光谱发现，并成为了得到表征的共价金属-金属键的最早的例子之一。 其它多汞阳离子还有线性的Hg2+3和Hg2+4离子，三角形的Hg4+3离子以及一系列的链状或层状多聚阳离子。 (zh)
