Zeolite Catalysis and Synthesis

Abstract The bulky gallium chlorides, (t-BuGaCl2)2 (1) and (Cy2GaCl)2 (Cy = C6H11) have been prepared via the reaction of GaCl3 with t-BuLi and CyMgCl, respectively. The structures of 1 and 2 have been determined by X-ray methods. Crystals of 1 are monoclinic, space group P21/c, with a = 6.937(4), b = 6.877(5), c = 17.11(1) Å, β = 95.65(6)[ddot], Z = 2; crystals of 2 are monoclinic, space group P21/c, with a = 10.389(2), b = 11.580(3), c = 11.198(2) Å, β = 95.96(2)[ddot], Z = 2. The R values for 1 and 2 are 0.0617 and 0.0681, respectively. The solid state structures of 1 and 2 consist of chloride-bridged dimers.
