The complex (YbCl2. 15-crown-5][AlCl2Me2] has been prepared by the reaction of YbCl3. 15-crown-5, and AlMe3(1:1:4) in toluene. The colourless, air-sensitive crystals belong to the orthorhombic space group Pnma with a = 11.313(7), b = 10.907(5), c = 17.716(7) Å, and Dc= 1.81 g cm-3for Z = 4. The structure was refined to R = 0.048 based on 1502 observed reflection. The Yb atom is displaced 0.20 A from the plane of the crown ether, and the Yb-O bond distance range from 2.23-2.32 A.
