Cadmium(I) tetrachloroaluminate is the inorganic compound with the formula Cd2[AlCl42, a tetrachloroaluminate of cadmium(I). It was the first compound reported (1961) that contained cadmium in the +1 oxidation state and features a cadmium–cadmium bond.
Cd2[AlCl42 was originally prepared by dissolving Cd metal in molten CdCl2 followed by the addition of AlCl3. [2]
Subsequent studies of the Raman vibrational spectrum indicated the presence of a cadmium–cadmium bond, [3] which was confirmed by two separate X-ray diffraction studies of single crystals. [4] [5] The compound can therefore be compared to mercury(I) (mercurous) compounds (such as mercury(I) chloride), which contain Hg2+2. The Cd−Cd single bonds are part of ethane-like Cd2Cl6 units sharing vertices with AlCl4 units, with a Cd−Cd bond length reported as 257.6 pm [4] or 256.1pm. [5]
Cd2[AlCl42 is diamagnetic. It contains no unpaired electrons and reacts readily with water disproportionating to give Cd metal and Cd2+.
