[CH3C6H5BiCl2][AlCl4] and [(CH3)6C6BiCl2] [AlCl4]–Compounds containing η6‐Arene‐Complexed BiCl Units

The ability of AlCl3 to abstract chloride ions from BiCl3 makes it possible to synthesize the title compounds in the presence of toluene and hexamethyl benzene, respectively. 1, the hexamethylbenzene complex, is an arene‐stabilized, dimeric dichlorobismuth(III) tetrachloroaluminate. The coordination of bismuth can be described as strongly distorted octahedral; five Cl ligands (two shorter, three longer Bi–Cl distances), one arene ligand. equation image
