Twenty-three dinuclear aluminum halide complexes based on bis(beta-diketiminate) ligands with various flexible and rigid bridging groups have been synthesized and fully characterized by NMR and IR spectroscopy, cyclic voltammetry, and elemental analysis. In addition, nine complexes were structurally characterized by means of single-crystal X-ray diffraction. Attempts to reduce the dinuclear species using C8K remained unsuccessful, but the reduction potentials investigated by cyclic voltammetry indicate the principle feasibility.
