Abstract | {The aluminum, gallium, and indium tris(ligand) complexes of 3-hydroxy-2-methyl-1-n-propyl-4-pyridinone and 1-n-butyl-3-hydroxy-2-methyl-4-pyridinone have been prepared and characterized. All six compounds were prepared in a one-pot synthesis from maltol, n-propyl-, or n-butylamine and an appropriate metal(III) salt, and were completely characterized (IR, FAB-MS, H-1 NMR, Al-27 NMR, elemental analysis). Three of the six complexes were studied by single-crystal X-ray diffraction and were found to form trihydrates, unlike their 1-methyl and 1-ethyl analogues, which formed dodecahydrates. The n-butylpyridinone complex Al(C10H14NO2)3.3H2O (Al(nbp)3.3H2O) and n-propylpyridinone complexes Al(C9H12NO2)3.3H2O (Al(npp)3.3H2O), and Ga(C9H12NO2)3.3H2O (Ga(npp)3.3H2O) were essentially isostructural, crystallizing in the space group P3BAR with the following crystal parameters for Al(nbp)3.3H2O (Al(npp)3.3H2O, Ga(npp)3.3H2O): a = 15.885(1) (15.328(1), 15.367(2)) angstrom |
