Abstract

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.
