The synthesis and characterization of the dinuclear group 13 heterocyclic carboxaldehyde thiosemicarbazone complexes (Me2M)[NC5H4CMeNNC(S)NR](MMe2) (M = Al, R = Me (1), C3H7 (3), Ph (5); M = Ga, R = Me (2), iC3H7 (4), Ph (6)) and acetophenone thiosemicarbazone complexes (Me2M)(CH3RCNNC(S)NR′)(MMe2) (M = Al, R = Ph, R′ = Ph (7); M = Al, R = CH3, R′ = CH3 (9); M = Ga, R = Ph, R′ = Ph (8); M = Ga R = CH3, R′ = CH3 (10)) are described. Compounds 1-6 were prepared by the reaction of MMe3 (M = Al, Ga) with 2-acetylpyridine 4-alkylthiosemicarbazone in toluene. Compounds 7-10 were prepared using MMe3 (M = Al, Ga) in toluene with acetophenone 4-alkylthiosemicarbazone under anaerobic conditions. These compounds, 1-10, have been characterized by microanalysis, NMR (1H, 13C, 27Al) spectroscopy, and single-crystal X-ray diffraction. X-ray single-crystal diffraction analyses reveal that compound 3 is a dinuclear aluminum compound with coordination numbers of five and four and compound 8 is a dinuclear gallium compound in which each gallium atom is four-coordinate.
