The bis-dimethylamido gallium chloride, [NMe2(μ-NMe2)GaCl]2(1) may be prepared by the reaction of two equivalents of lithium amide with GaCl3. The amido ethoxide gallium chloride, [TMP(μ-OEt)GaCl]2(2), (TMP-tetramethylpiperidide) is formed in the reaction of lithium amide with GaCl3 in diethylether. The structures of 1 and 2 have been determined by X-ray methods. Crystals of 1 are orthorhombic, space group P222I22, with a = 8.428(4), b= 15.10(1), c= 13.138(6) A, Z=4. Crystals of 2 are monoclinic, space group P22/n, with a= 8.542(1) b= 12.457(1), c= 12.959(1) A, β = 95.483(9), Z = 2. The R values for 1 and 2 are 0.066 and 0.054, respectively. The solid state structure of 1 consists of a nitrogen-bridged dimer, while 2 consists of an oxygen-bridged dimer.
