The reaction of InCl3 with InX (X = Cl, Br, I) in a dichloromethane/toluene/N,N,N′,N′-tetramethylethanediamine (tmen) mixture yields the bis(tmen) adducts of Cl(X)InCH2InCl2. X-ray crystallography of compounds with X = Cl and Br has shown that these are the first examples of diindium methylene structures, with an average In-C-In angle of 117.6°. For Cl2InCH2InCl2·2tmen: cell constants a = 7.782 (1) A?, b = 21.192 (3) A?, c = 14.366 (3) A?; space group Pccn; R = 0.021, Rw = 0.021. For Cl(Br)InCH2InCl2·2tmen: cell constants a = 7.849 (2) A?, b = 21.205 (3) A?, c = 14.374 (4) A?; space group Pccn; R = 0.024, Rw = 0.027. The structural results are compared with those for other organoindium species, and the mechanism of the formation of these compounds is discussed in terms of the available preparative and spectroscopic evidence.
