|Section2= |Section3= }} Cadmium(I) tetrachloroaluminate is the inorganic compound with the formula Cd2(AlCl4)2, a tetrachloroaluminate of cadmium(I). It was the first compound reported (1961) that contained cadmium in the +1 oxidation state. Subsequent studies of the Raman vibrational spectrum indicated the presence of a cadmium–cadmium bond, which was confirmed by two separate X-Ray diffraction studies of single crystals. The compound can therefore be compared to mercury(I) (mercurous) compounds (such as mercury(I) chloride), which contain . ==Preparation and properties== Cd2(AlCl4)2 was originally prepared by dissolving Cd metal in molten CdCl2 followed by the addition of AlCl3. :CdCl2 + Cd → Cd2Cl2 :Cd2Cl2 + 2 AlCl3 → Cd2(AlCl4)2 Cd2(AlCl4)2 is diamagnetic. It contains no unpaired electrons and reacts readily with water disproportionating to give Cd metal and Cd2+. It has a complex structure that contains ethane-like Cd2Cl6 units sharing vertices with AlCl4 units, with a Cd–Cd bond length reported as 257.6 pm〔 or 256.1pm.〔 200px 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cadmium(I) tetrachloroaluminate」の詳細全文を読む スポンサード リンク
